Custom built power supplies with single phase inputs

Custom built power supplies with 3 phase inputs

DC outputs from below 1A up to 500A

Open type or enclosed, portable or fixed

Naturally air cooled or forced air cooled

With accessories such as metering, indicators, mains

isolators, with input fuse or MCB or output semi conductor

fuse protection

Output smoothing available on some types

A comprehensive range of custom built power supply units with either single or three phase inputs.

Single phase units have a high output ripple of 48% with conventional full wave bridge rectifiers. Three phase units have a much lower output ripple of 6% with conventional full wave bridge rectifiers. These values of ripple can be reduced to lower levels with output smoothing, where practical.

Units can be open or enclosed and can be supplied with separate transformers and bridge rectifiers with suitable heat sinks. Cooling can be either naturally air cooled or forced air cooled with the use of AC or DC fans.

Fully customised units can be produced with accessories such as AC and DC metering, status indicators, mains isolators switches and input and output protection.
