POWER SUPPLY DESIGN EXCELLENCE
The Powerstax A0750 series of front-ends power modules is specifically designed to operate as an integral part of a complete distributed power system, with or without battery backup. A full complement of protection, alarm and control features has been incorporated into the power unit to provide the versatility of applications. When up to 3 x A0750 are used with the 1U high R2250 19“ rack, a total 2,250W (or 1,500W of N+1) of 24VDC or 28VDC output can provide a low profile, flexible and scalable solution. The flexible feature set makes this front-end power module an excellent choice for applications requiring modular AC-to-DC power systems such as distributed power and DC UPS.
