54-184
12.6VAC 6.3VAC filament transformer manufactured for Heath Company vintage electronic test equipment.Quick Specifications & ApplicationComponent Type: Filament TransformerPrimary Device Compatibility: Used natively in the Heathkit IP-17 (and later SP-2717A) Regulated High Voltage Power Supply.Partner Transformer: It operates alongside the separate Heathkit 54-185 plate transformer inside the power supply chassis.Primary FunctionIn the IP-17 / SP-2717A circuits, this specific component delivers isolated AC filament step-down voltages (such as 6.3V and 12.5V AC taps) required to heat the vacuum tube cathodes used for regulating the unit's high-voltage DC output - The Heathkit 54-184 filament transformer features dual input primaries and an isolated secondary winding designed for a total power output rating of 25 Volt-Amperes (VA).Its exact voltage and current specifications, retrieved directly from the original Heathkit SP-2717A and IP-17 technical schematics, break down as follows:Primary (Input) SideVoltage Rating: Configurable for 120V AC (wired in parallel) or 240V AC (wired in series) at 50/60 Hz.Secondary (Output) SideThe secondary filament winding is center-tapped and can be utilized in three different wiring configurations:6.3 Volts AC configuration: Rated for a maximum current of 4.0 Amperes.12.6 Volts AC configuration: Rated for a maximum current of 2.0 Amperes.Combined configuration: Both output taps can be used simultaneously, provided the cumulative electrical load does not breach the core 25 VA threshold
