UL-1236 Compliant Battery Chargers

The UL-1236 standard is a well-established and widely specified standard for batteries in standby and emergency engine-driven equipment such as power generators and fire pumps. UL1236 sets demanding minimum requirements for battery charging power/time, panel controls and instruments, and fault alarm/warning/protection features.

Computronic Controls has extensive experience of UL1236 compliant chargers and system requirements. We have a range of both UL-recognised (open-frame) and UL-listed (fully enclosed) models to suit your genset, firepump or standby engine application.
