Dreiphasige Stromversorgungen mit reduzierter Pulsation
Three-phase DC supplies with Graetz’s bridge rectifier with connections B6 or B12 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.
Power supplie EZ3W - with smoothing capacitor, used for IN ≤ 30 A
Power supplie EZ3P - with 12 - pulse circuit, used for IN > 30 A
