Elmdene TR 24V Transformer Rectifier
£53.91 – £63.88
Summary
The enhanced Elmdene TR 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 TR 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 units now have an expanded 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.
