Three-phase DC supplies with Graetz’s bridge rectifier with connection B6 are designed for users who need for their receivers an unstabilized DC voltage.
DC-supplies are equipped with a LED indicating the current state of the operation. Standard designs of power supplies are prepared for mounting on mounting brackets.
On request power supplies can be supplied with two types of protection: against fault and overload protection.
