SITOP Add-On Modules
The redundancy module guarantees stable 24Vdc power by decoupling two power supplies in parallel operation. The module monitors both power supplies and makes sure that the stand by power supply immediately takes over when the output voltage of the operating power supply drops below the (adjustable) threshold voltage. For applications above 20 amps one redundancy module per power supply is required. The SITOP PSE201U buffer module bypasses short-term power failures lasting a few seconds and can be used with all 24 V power supplies of the SITOP smart or SITOP modular product lines. 100msec at 40A, 800msec at 5A, up to max. of 3 sec at low load current. Connects in parallel with the basic unit, DIN rail mounting is possible at any location in the switching cabinet.,The signaling module can be snapped onto the left side of the basic device. The module offers floating signal contacts ("output voltage ok" and "ready for operation ok") and a signal input for remote ON/OFF of the basic device.
