Supplier for 30535 in USA – Torotel Power Transformer for Aerospace and Defense Applications

 If you are searching for a supplier for 30535 in USA, it is important to identify the complete component reference before placing an order. The part number 30535 is used in more than one product category across electronic-component databases, so manufacturer and application information should always be verified. In aerospace and defense component databases, however, 30535 is identified as a power transformer associated with NSN 5950-01-324-3278 and CAGE 07388. The same NSN is cross-referenced to HS5564-1 and PC5-1558, providing useful identification information for sourcing and replacement.

The available NSN data identifies this component as an open-construction, single-phase power transformer with one primary and one secondary winding. It is designed for applications where controlled AC voltage conversion and electrical isolation are required, making it particularly relevant to legacy aerospace, military, avionics, and specialized electronic equipment.

 

Overview of 30535 Power Transformer

The 30535 is listed under Federal Supply Classification 5950, the classification covering coils and transformers. Its associated NSN is 5950-01-324-3278, while the same NSN is also associated with model HS5564-1 and cross-reference PC5-1558.

According to the available NSN specifications, the transformer has an open enclosure, two mounting facilities, and a mounting arrangement using unthreaded holes. It uses five tab solder-lug terminals for electrical connections. The transformer has one primary winding and one secondary winding, making it a relatively straightforward single-phase power-transformer configuration.

The listed overall dimensions are approximately 2.810 inches in length, 1.380 inches in width, and 1.630 inches in height, with a mounting-hole diameter of approximately 0.188 inches. The mounting-facility centers are specified at approximately 2.375 inches. These mechanical characteristics are especially important when replacing a transformer inside an existing enclosure because the replacement must fit the original mounting structure.

Key Parameters and Features of 30535

The most detailed public specification associated with 30535/NSN 5950-01-324-3278 identifies a 400 Hz frequency rating, a 16 VA maximum transformer power rating, and single-phase input/output. The listed maximum operating temperature is 105°C. The transformer also incorporates an internal winding shield brought out to a terminal, which can be important for controlling unwanted capacitive coupling and improving isolation between electrical circuits.

The documented winding configuration consists of one primary and one secondary. The NSN record lists the primary winding at 115 VAC and the secondary at 26 VAC, with the secondary rated at 600 mA AC. These values correspond to approximately 15.6 VA on the secondary, consistent with the listed 16 VA transformer class.

These specifications make the 30535 suitable for equipment requiring a relatively low-power AC secondary supply while maintaining galvanic separation between the source and load. Engineers should nevertheless verify the exact nameplate and equipment documentation before substitution, particularly when the component is being used in safety-critical or flight-related equipment.

Applications of 30535 in Aerospace and Defense Equipment

One of the most significant application characteristics of the 30535 is its association with the AH-64 Apache helicopter. The NSN record identifies the end application as the Apache AH-64, demonstrating that this transformer belongs to a class of components used in specialized aerospace equipment.

In aerospace electronics, power transformers can serve several important purposes. They may provide isolated low-voltage AC power to control circuits, instrumentation, signal-conditioning electronics, monitoring equipment, or other subsystems. Electrical isolation is particularly valuable in complex systems because it helps prevent unwanted direct electrical connections between different circuit domains.

The 30535's 400 Hz rating is also consistent with the type of power environment historically associated with aircraft electrical systems. Aircraft commonly use higher-frequency AC power than conventional commercial mains systems because higher frequency permits magnetic components to achieve useful power-transfer characteristics with smaller cores and lower weight. For aerospace equipment, minimizing size and weight while maintaining electrical performance is a major engineering consideration.

Because the 30535 is associated with legacy military equipment, replacement requirements may arise many years after original production. Maintenance organizations may therefore need to source original or correctly cross-referenced transformers rather than redesigning an entire power subsystem.

Related Model HS5564-1

HS5564-1 is one of the most important related identifiers when researching 30535. The NSN database lists HS5564-1 as a cross-reference for NSN 5950-01-324-3278, alongside 30535 and PC5-1558.

This cross-reference is useful for aerospace maintenance because an engineering drawing, maintenance manual, procurement document, or existing component may use a different identifier from the one shown in a supplier database.

HS5564-1 is described as a power transformer with the same general configuration: one primary and one secondary, five solder-lug terminals, unthreaded-hole mounting, and 115 VAC primary to 26 VAC secondary operation. The available NSN record also gives the same 400 Hz rating and 16 VA maximum transformer rating.

When sourcing replacement units, engineers should therefore search both 30535 and HS5564-1, but should confirm the NSN and physical/electrical characteristics before treating them as equivalent.

Related Model PC5-1558

Another important cross-reference is PC5-1558, which is also associated with NSN 5950-01-324-3278. Government and component databases identify PC5-1558 as a power transformer with the same open enclosure, five solder-lug terminals, and unthreaded-hole mounting configuration.

For aerospace repair and procurement teams, this type of cross-reference can substantially improve sourcing efficiency. A discontinued component may be difficult to find when searched under only one part number, while the corresponding military stock number or alternate manufacturer reference can reveal additional supply channels.

PC5-1558 is therefore particularly relevant when maintaining equipment documentation that uses an alternate reference rather than the 30535 manufacturer SKU.

Other Related Aerospace Power Transformers

The broader Torotel-associated component family includes numerous other power transformers, including 29242, 29243, 29246-2, 29247, 29248, 29249, 29554, 29876, 30047, 30163, and 30204. These parts are also classified under FSC 5950, but their electrical configurations and mechanical designs differ. For example, the available database identifies 29242 as an 8-terminal transformer, 29243 as a 12-terminal transformer, and 30204 as a 15-terminal transformer.

These related components illustrate the variety of transformer configurations used in aerospace and defense electronics. A higher terminal count can indicate multiple windings, taps, or more complex power-distribution requirements. Some models may be fully enclosed, while others use different mounting systems.

The 30047 example is particularly useful for comparison because its published data identifies multiple secondary winding voltages—25 VAC, 36 VAC, and 17 VAC—with a 115 VAC primary and 400 Hz frequency rating. This demonstrates how aerospace power transformers can be customized for several isolated supply rails within a single electronic assembly.

Engineers should not substitute these related models simply because they share the same FSC classification. Voltage, current, VA rating, frequency, winding configuration, mounting dimensions, terminal arrangement, insulation, and shielding requirements all need to match the original equipment.

Why 30535 Is Important for Legacy Equipment

The 30535 is especially relevant to maintenance organizations because specialized aerospace systems often have much longer operational lifetimes than consumer electronics. A transformer that was originally installed decades ago may still be required to support equipment undergoing overhaul, depot maintenance, restoration, or parts replacement.

The ability to identify a component through several references—30535, NSN 5950-01-324-3278, HS5564-1, and PC5-1558—can make obsolete-component sourcing much easier.
