Elmdene 24Vdc 1A Low Profile Door Retainer Power Supply Unit
The new Elmdene TRS range of power supplies has been specifically designed for access control applications that require remote control of the power supply output. A typical example being where a TRS power supply unit is used to power magnetic door retainers; utilising a signal from the fire panel in order to switch off the output to the doors in the event of a fire alarm activation.
The TRS PSU has a range of input options which includes the detection of a normally closed contact going open and also removal of a 24V dc signal to provide a fully fail safe operation mode (BS 7273 Compliant).
The three control input options for remote control of the output are as follows:
Removal of an external 24V dc supply (BS 7273 Compliant)
Opening of a normally closed volt-free contact
Closing of a normally open volt-free contact
LED status indicators provide quick diagnostics showing the presence of a mains input and output fuse failure. The products use energy efficient switch mode technology and have a universal mains supply input (90—264V ac).
