MPS-1
Metering Pulse Supply
GENERAL DESCRIPTION
The MPS-1 Meter Power Supply, a low-cost DC power supply option, provides an isolated low-voltage DC wetting voltage designed specifically for KYZ pulse metering applications. Packaged in the convenient SSI “small footprint” case, the MPS-1 can be used in any application where a wetting voltage is needed to go through a KYZ pulse initiator and into another pulse input device such as a SCADA system, RTU, Energy Management System, KYZ pulse totalizer, electric meter pulse input or other telemetry or control systems which accept pulses.
The MPS-1 is available in a variety of output voltages between 3VDC and 24VDC. The output voltage needed can be specified by adding the DC voltage after the MPS-1 model number (i.e. MPS-1-24 to indicate a 24VDC output).
The power supply’s low-current design provides up to 40mA for the pulse metering circuit. The output is internally current-limited and provides a fuse to prevent damage in the event of a short circuit condition. In addition, the MPS-1 power supply includes MOV transient suppression devices on both the 120/208-277 power supply input and the DC output.
