Product Description

Hoffman Controls – 905-M480VMA(48)2 905 Series SCR’s are available in two configurations. The Master SCR is inclusive of a 905-M (M Suffix) Series Interface which is capable of directly accepting proportional analog signals. The 905-S (S Suffix) Slave SCR is capable of only accepting a DC “Pulse Width” Modulated signal. The 905-S SCR can be converted to a 905-M by adding a 901 Series Interface Logic to the 905-S. These Class I Line voltage controllers are designed to provide the maximum reliability of proportionally controlling power to a resistive single phase or three phase load. Limitations may preclude total line currents of 48 Amps per circuit; the number of circuits are limited only by the load being imposed. The 905-M and 905-S Series multi-voltage power switching modules have been designed for two voltage ranges. 208V through 480V AC at 50 or 60 hertz, and 208V through 600V AC at 50 or 60 hertz. The example of the model number below indicates the nomenclature that readily describes the various features, function or limitations of the model.
