NTN28K0 Series

28kW regulated high voltage AC-DC power supplies with isolated output voltages from 0-6.5VDC to 0-350VDC

The NTN28K0 series are highly stable linear regulated power supplies with low ripple and an isolated output. Featuring thyristor (SCR) pre-regulation followed by transistor regulation to provide double stabilization.

The power supplies can be operated in local, analog (optional) and digital (optional) operating modes.

Sense line connections provide feedback compensation for voltage drop in the load lines.
