DIN Rail Mounting 1 or 3 Phase Voltage Monitor (VSU)
Code: VSU
TECHNICAL FEATURES
* Detects Phase Failure Or Drop In Voltage On Any Phase Below A Preset Specified Level
* Single Or Three Phase Capability
* SPCO Relay Contacts Rated At 5 Amps
* Standard Or Customer Specified ‘Cut In’ Voltage
* Standard Or Customer Specified ‘Drop Out’ Voltage
OPERATIONAL FEATURES
On application of a supply voltage greater than the ‘Cut In’ voltage, the internal relay will energise and the ‘POWER’ and ‘RELAY’ LED’s will illuminate. If the supply voltage (or any phase) falls below the ‘Drop Out’ voltage, the relay will de-energise and the ‘RELAY’ LED extinguishes. The VSU will only return to its original state if the supply voltage again exceeds the ‘Cut In’ voltage.
