Our process

From design to dispatch.

01

Circuit design

Microprocessor-controlled correction logic, built around a defined working range for each model.

02

Component sourcing

Branded relays and circuit breakers (SKN Bentex) rather than unmarked generic parts.

03

Assembly

Assembled and wired in-house, with high-low cut off and time-delay relay protection built into every unit.

04

Computerised testing

Every unit is powered up and checked on test equipment before it's packed, not sample-batch tested.

05

Dispatch

Serial-numbered and boxed with the model's full spec sheet printed on the carton.

What's built into every unit

Not just a transformer in a box.
