ROBERTSHAW 4548 HOT SURFACE IGNITION MODULE HS780-3.

HOT SURFACE IGNITION MODULE HS780-3

The hot surface ignition module HS780-3 is a solid state, true triac type high voltage ignition module that operates as an electronic switch. Its output voltage ranges from 1.2 to 10 Volts peak (5 to 30 VDC RMS). It is normally open in the "ON" condition and can be connected directly across the power line or normal "hot" circuit supply to feed energy into the control circuits of gas fired ovens, heating equipment, pizza ovens and deep fat fryers. The common contacts are normally closed and energized with an internal resistor. When a trigger pulse from a metal-oxide

The Category III, HS780-3 uses 4 breakers to control 3 heating circuits. Each circuit is rated at 40 amps with 71/2 kV of isolation between each circuit allowing two circuits to share one neutral (or ground) lead. This hot surface ignition module works with the HS780 control panel and the HS782 automatic transfer switch.

The HS780-3 is a hot surface ignition module for the HS740 and HS770 series cooktops. This model has 3 terminal connections and requires 120VAC @ 50/60Hz. The HS780-3 replaces Part #: HS780.

Unlike a flame sensor, the HS780-3 hot surface ignition module allows the operator to choose when to turn on high power. This is vital in situations where the customer may wish to use lower power levels during pre-heat, and higher power levels when fast cook times are required. Either way requires precise temperature monitoring that this module provides.

The HS780-3 Surface Ignition Module is for use with Robertshaw low pressure gas valves. It is a fail-safe, surface mounted ignition module with a manually operated solenoid that controls the natural gas valve pilot. The ignition module is made of stainless steel and withstands rugged over the road environments.

The HS780-3 is a surface mount ignition module that consists of a high spark quality unit incorporating an igniter and ionization area assembly.

The HS780-3 is a self igniting ignition module. The ignitor is maintained at above 2500°F by a ceramic heating element, which is energized by an internal resistance.
