WPG-1E Wireless Pulse Generator

WPG-1E Wireless Meter
Pulse Generator

The WPG-1E Wireless Meter Pulse Generator integrates New advanced meters with legacy KYZ pulse metering. Using a Wifi interface, the WPG-1E receives usage data from the meter, interprets power usage, and converts it into KYZ pulses.  With the WPG-1E, pulses are synthesized without having an actual KYZ output at the meter. By doing this, the utility can implement the new advanced meters and still provide pulses to customers that may need them.

The WPG-1E incorporates a Wifi radio module and two independent KYZ pulse outputs. As the WPG-1E receives periodic data from utility’s meter, the data is read and interpreted to obtain the current demand and energy information. Accumulated energy is computed and pulses are outputted according to a selected pulse type and value.

All system settings are accomplished through a USB programming port that provides for pulse type, pulse value, meter multiplier, output mode, and pulse timing. The output is selectable as either Form A (2-Wire) or Form C (3-Wire) and operates in either the momentary or toggle mode, respectively. The momentary mode has six pulse width time settings: 25mS, 50mS, 100mS, 200mS or 500mS and 1000mS. The toggle mode toggles back and forth to the opposite state upon each new pulse being generated which emulates the classic KYZ Pulse output. There are four LED’s, two red and two green, one set for each of the two outputs, which show the pulse output status.

The output pulse value is selectable from 1 to 99999 watt-hours, va-hours or var-hours per pulse.  Each of the two outputs may be set independently for type and value of the pulse.  A meter multiplier of 1 to 99999 may be programmed into the WPG-1 using the SSI Universal Programmer software. A 30mS fixed minimum-off time delay prevents pulses from occurring too rapidly. Bright red, yellow and green LEDs monitor the system communications status and provide an easy and immediate visual system check without test equipment.

The Wifi module must first be paired with the meter, a process that is performed by the participating utility. Once paired with the meter, the WPG-1E’s Wifi module will begin receiving information from the meter and generating pulses.

The WPG-1E is compatible with Self-Contained or Instrument-rated electric meters. The WPG-1E's USB programming port is used to enter the specific site’s meter multiplier from 1 to 99999. Each output of the WPG-1 can be configured to generate kWh, kVAh or kVARh pulses in either delivered (positive or forward) or received (negative or reverse) quantities.
