Siemens SITOP PSU300B Power Supply Optimizes Battery Charging

Offers 24V DC/17A Three Phase Power
Useful in Worldwide Applications
Compact Design Requires Little Mounting Space

The new SITOP PSU300B 24V DC/17A three phase power supply from Siemens Industry Sector optimizes overload protection when charging 24V lead batteries. The power supply’s wide-range-input for 3AC 320 to 575 volts also make it applicable for standard, industrial applications on three-phase network connections worldwide.

At just 70mm wide, the 93 percent efficient PSU300B requires little mounting space. Plug in terminals eliminate time costly and consuming wiring. The integrated relay contact allows for transparency into the operating states of the power supply and allows further processing of these states in the upper level control system.

An integrated signaling, or relay, contact easily integrates the power supply into upper level control systems, such as PLCs. This allows transparency into the operating status of the PSU300B.
