The FSP450-H35-A54 is a single-output AC-DC converter from FSP Technology Inc. designed for open-frame applications. It accepts a universal input voltage of 90 to 264 VAC at 47 to 63 Hz. The main output provides 54V at 8.33A, with a maximum power of 200W under natural convection cooling and up to 450W with forced air cooling.
This converter features active power factor correction (PFC) with a minimum power factor of 0.99 at 115VAC and 0.96 at 230VAC. It includes protections against overvoltage (OVP), overcurrent (OCP), overtemperature (OTP), and short circuits. The hold-up time is at least 10 ms at 115VAC, and the turn-on delay is ≤3 seconds. The transient response is better than 4% for a 25% step load change, recovering to 1% within 500 µs.
Operating temperature range is -20 to +70°C, with linear derating from 100% at +50°C to 50% at +70°C. The unit is Class-I and complies with IEC 62368-1 safety standards. EMC performance meets EN55032/EN55035 and FCC Class B for both conducted and radiated emissions. The dimensions are 127.0 x 76.2 x 35.6 mm (5.0 x 3.0 x 1.4 inches).
