Voltage Converter

The Voltage Converter is a cost-effective way of converting 24 VAC or VDC to 5, 12, 15, or 24 VDC for use on peripheral devices that require DC voltage. The converter is available with a 350 mA output. The mounting system allows for 2.75” snaptrack, DIN rail or surface mounting.

It is often desirable to convert to DC power as it eliminates the AC power “noise” which can affect the room sensor readings. Tests show that fluctuating and inaccurate signal levels are possible when AC power wiring is present in the same cable as the signal lines. To minimize the AC voltage noise, the DC converter must be mounted as close to the controller as physically possible. Do not mount the converter at the sensor end of the wire, the AC will still couple into the sensor signal if you do.
