## Description

The VOF-225C-48-CNF is a 225 W enclosed AC-DC power supply from the VOF-225C series, engineered for high-efficiency power conversion in industrial, consumer, and ITE environments. Featuring a universal input voltage range of 85 to 264 Vac (or 120 to 370 Vdc) and active power factor correction (PFC achieving up to 0.99 at 115 Vac), this unit delivers a regulated 48 Vdc output at a maximum current of 4.7 A. The enclosed mechanical format measures 103.4 × 62.0 × 37.0 mm, utilizes natural convection cooling, and incorporates an adjustable output trim potentiometer alongside dedicated connections for an external auxiliary cooling fan (12 V, 6 W max).

This power supply meets stringent global compliance standards, certified to IEC/EN/UL 62368, EN 60335, and EN 61558 safety specifications while supporting both Safety Class I (with PE) and Class II (without PE) installations. It features comprehensive internal protections including latching over-voltage protection set at 60 Vdc, continuous hiccup-mode short circuit protection, over-current protection, and auto-recovery over-temperature protection. Additionally, the unit exhibits low leakage current (< 0.1 mA), minimal standby power consumption (0.5 W), and robust EMC performance compliant with CISPR32/EN55032 Class B conducted emissions.

Notes: 1. When adjusting the output voltage care should be taken never to exceed the stated output power or output current of the unit. 

2. At full load, nominal input, 20 MHz bandwidth oscilloscope, tip & barrel method, output terminated with 10 μF electrolytic and 0.1 μF ceramic capacitors. Under light load conditions (<15%) the measurement may double in an effort to maximize converter efficiency. 

3. At 230 Vac.
