Product Introduction

The UV-C controller separates germicidal operation from ordinary room-light switching. Its cleanable front panel carries a key switch, timer display, start/stop controls and status indicators. Inside the enclosure, a contactor or relay output switches the UV-C load while low-voltage terminals accept door contacts, occupancy sensors, warning beacons and remote emergency-stop devices.

Key Features

A keyed enable switch limits cycle initiation to authorized personnel.

The programmable delay provides a defined exit interval before lamp energization.

A digital display shows remaining treatment time and operating state.

Dedicated safety inputs interrupt the output when a monitored door opens or occupancy is detected.

Separate relay terminals operate external beacons and audible warnings.

Customer Product Concerns

A basic timer alone cannot manage warning, authorization and interruption functions required around an unattended UV-C cycle.

Anyone can start a germicidal circuit from a normal wall switch.A key-controlled enable stage restricts initiation to designated operators.

Personnel have no time to leave after pressing start.An adjustable countdown drives warnings before the power relay closes.

Opening a door does not stop an independent timer output.Hardwired safety inputs drop the UV-C contactor immediately on an interlock event.

The operator cannot see whether a cycle ended or was interrupted.Distinct display states report standby, delay, active, complete and fault conditions.

Typical Applications

Fixed UV-C room systemsPass-box germicidal circuitsDuct irradiation controlsLaboratory treatment rooms
