PSUA220D48 series power box is used when users’ power supply is AC and lights’ operation voltage is 48VDC.
With high-quality converter(s) with over 90% efficiency, the power box is capable of converting universal AC (90-264VAC) to 48VDC (48-55VDC). The power of the converter box depends on the load power of obstruction lights.
DIN-rail terminal blocks save wiring time and enhance wiring safety. A 2P circuit breaker is effective in protecting converters from overload. A surge protector enhances protection against voltage fluctuation and lightning strikes.
The power box can be used for a single obstruction light, for example, a 480W power box for a F86465 unit. In some cases, a power box with high power is used for multiple medium intensity lights in a system.
