HC15-3-A

The Bel Power Solutions HC15-3-A is a linear AC/DC converter designed for ITE (Commercial) applications. It provides a single output with a power rating of 45W and a current of 3A.

Key electrical specifications include a 3 kV voltage rating, 55% efficiency, and adjustable output with remote sense capabilities. The unit operates within a temperature range of 0°C to 50°C and features automatic current limit/foldback for short circuit protection. It also includes built-in overvoltage protection on 5V models, with optional protection available for others.

This converter is designed for chassis mounting. Its dimensions are 142.8mm in length, 123.7mm in width, and 74.9mm in height. The AC input range is wide, supporting 100, 120, and 240 Vac with a frequency tolerance of 47 to 63 Hz. The datasheet indicates stability of ±0.05% for 24 hours after warmup and a temperature coefficient of ±0.01%/°C maximum.

Additional features mentioned in the datasheet include remote sensing with open sense lead protection (except HA & HTAA series), logic inhibit, and current-share for F & G models. The unit meets vibration standards per Mil-Std-810D. MTBF is rated at 200,000+ hours per MIL-HDBK-217D for most units. All electrolytic capacitors are rated at 105°C, and transformer insulation meets Class F (155°C). It exceeds FCC and CISPR22, Class B conducted emissions standards.
