Professional diagnostic and board-level repair service for this Red Baron RB-14/28-25 Power Inverter/ Charger.

Red Baron RB-14/28-25 Power Inverter/ Charger industrial electronic unit

The Red Baron RB‑14/28‑25 is an aircraft ramp power unit that supplies filtered 14 V or 28 V DC at up to 25 A, used for avionics testing and battery charging. Common failure points in this class of APUs include input AC filtering capacitors degrading, output voltage regulator ICs failing, and over‑current protection relays tripping due to shorted load paths. First‑check diagnostics: verify the 115 V/60 Hz input is within spec and that the unit’s internal fuses are intact; measure the regulated DC output with a multimeter while selecting 14 V or 28 V mode, noting any voltage droop or hum; inspect the front‑panel meters and indicator LEDs for fault codes or abnormal readings.
