Wireless Meter Pulse Generator

MPG-3SC

The SSI MPG-3SC Wireless Meter Pulse Generator is our third-generation Zigbee Pulse Generator, designed for utilities that need AMI smart meter integration with legacy KYZ pulse metering in a rugged, weatherproof package. Using Zigbee® radio technology, the MPG-3SC receives usage data from the meter’s HAN network, interprets power usage, and converts it into KYZ pulses — all without requiring a physical KYZ output at the meter.

The MPG-3SC features an integral Zigbee radio module, two KYZ pulse outputs, and an additional Form A End-of-Interval (EOI) output, all housed in a fiberglass NEMA 4X enclosure. Settings are configured via USB programming port using the SSI Universal Programmer software. An optional MPG-3SC-R22 variant adds two input and two output isolation relay channels for hybrid wired and wireless configurations.

Product Highlights

Beyond standard KYZ pulse generation, the MPG-3SC adds End-of-Interval capability — a dedicated Form A output that signals the close of a metering interval, with programmable interval lengths (1–60 minutes) and pulse widths. This makes the MPG-3SC well suited for demand metering applications that require precise interval boundary signaling alongside energy pulse outputs.

The NEMA 4X fiberglass enclosure makes the MPG-3SC suitable for direct outdoor installation, while LED indicators for both pulse outputs and communications status enable quick visual confirmation without additional test equipment. Both unidirectional and bi-directional energy flow configurations are supported.

Features

The MPG-3SC equips utilities to implement the new advanced AMI meters and provide pulses to customers that may need them
  • Zigbee® HAN Network Input — wirelessly receives AMI meter data without a hardwired KYZ output at the meter.
  • Two KYZ Pulse Outputs — dual Form A (2-Wire) or Form C (3-Wire) solid-state outputs, each independently configurable.
  • End-of-Interval (EOI) Output — dedicated Form A output with programmable interval lengths (1, 5, 10, 15, 30, or 60 minutes).
  • NEMA 4X Fiberglass Enclosure — raintight and dustproof housing rated for harsh outdoor environments.
  • USB Programmability — pulse value, multiplier, output mode, and timing fully configurable via SSI Universal Programmer.
  • Bi-Directional Energy Support — Normal mode for delivered energy or Signed mode for delivered and received quantities.
  • LED Status Indicators — red, yellow, and green LEDs provide instant visual communications status check.
