GREEN POWER PRO 6 CONTACTOR

Description

GREEN POWER PRO 6 CONTACTOR is the six-way heavy-duty electrical contactor from Green Power that enables safe, reliable switching of multiple HID lighting circuits and other high-inrush loads from a single timer or environmental controller output, protecting control equipment from the surge currents that direct HID switching generates. We have been recommending Green Power contactors to UK growers since 2017 as an essential piece of electrical infrastructure for grow rooms running multiple lights from a single control point.

Why Contactors Are Essential Infrastructure for Multi-Light Grow Rooms

HID ballasts draw significant inrush current at switch-on — often ten times or more their steady-state running current — as magnetic components saturate and capacitors charge during the start-up transient. Standard timers and environmental controllers are rated for the continuous current they switch, not for these brief but intense inrush events. Switching HID ballasts directly from timer contacts causes progressive pitting and erosion of the contact surfaces, gradually reducing the quality of the switched connection and ultimately causing timer or controller failure. A contactor solves this by using the low-current timer or controller output to energise a coil, which closes a set of heavy-duty power contacts rated specifically for high-inrush switching duty. The six-way Green Power Pro contactor can switch six independent HID circuits from a single coil energisation — simplifying wiring and centralising switching in a single, appropriately rated device.

Wiring, Coil Voltage, and Installation

The Green Power Pro 6 contactor is wired with the load circuits (ballasts) connected to the main contact terminals, and the coil connected to the control circuit output from your timer or environmental controller. Verify the coil voltage matches your control circuit output — typically 230V AC for UK timers. Mount the contactor in a suitable electrical enclosure with adequate ventilation, as contactors generate some heat during operation. Ensure load cabling is sized appropriately for the combined current draw of all six circuits. For grow rooms running three, four, five, or six HID lights from a single timer, the Green Power Pro 6 is the correct, purpose-built solution for safe, reliable switching.
