Pulser Pulse Generator

P-1

The SSI P-1 Pulser is a handheld pulse generator designed to simulate a utility electric meter’s KYZ pulse output for testing downstream telemetry, recorders, energy management systems, and similar pulse-receiving devices. By connecting the P-1’s output directly to a receiving device, a technician can verify that the device is detecting and responding to pulses correctly — without requiring an active meter or live metering installation to be in place.

The P-1 provides either a Form A (KY, 2-wire) or Form C (KYZ, 3-wire) simulated output and offers three selectable pulse sources: a 1Hz precision pulse, a variable 1Hz to 10Hz pulse controlled by an onboard potentiometer, and an external pulse input for use with a function or signal generator. It is powered by a 12VDC plug-in wall transformer included with the unit, and its output is an optically isolated solid-state dry-contact rated at 100mA maximum — matching the contact rating of standard electric meters.

Product Highlights

The P-1’s three selectable pulse sources make it adaptable to a wide range of testing scenarios. The 1Hz precision mode delivers a stable, known pulse rate for verifying counting accuracy at downstream devices. The variable mode allows the tester to sweep across the 1–10Hz range to check device response across different demand levels.

The external input mode enables integration with a lab signal generator for custom pulse patterns not achievable with the built-in sources.

Bright red and green LED indicators display K-Y and K-Z continuity status at all times, confirming pulser operation at a glance without additional test equipment.

Features

The SSI P-1 Pulser simulates Form A or Form C meter KYZ pulse outputs at selectable rates for testing telemetry, recorders, and energy management systems.
  • Three selectable pulse sources — 1Hz precision pulse, variable 1–10Hz (potentiometer-controlled), or external pulse input for function generator use.
  • Form A and Form C output — configurable for either 2-wire (KY) or 3-wire (KYZ) simulated meter pulse output.
  • Optically isolated solid-state output — dry-contact output rated at 100mA maximum; matches standard electric meter contact ratings.
  • 12VDC plug-in wall transformer included — powers the unit from any 120VAC outlet; no batteries required.
  • Red and green LED indicators — display K-Y and K-Z continuity status at all times for rapid visual confirmation.
  • Polycarbonate enclosure — all powered components enclosed; polycarbonate base provides electrical insulation from mounting surface.
  • Portable handheld form factor — designed for bench test, field commissioning, and lab use.
