PPM1 Series

Precision Photomultiplier Power Supply Module

This compact, high-reliability, photomultiplier power supply module has considerable advantages in size, weight, and specification over other competitive units for photomultiplier applications—and for applications where 1 W output power is sufficient and high performance is essential.  Line, load, and ripple performance, together with many other aspects of the specification, are all you would expect from this professional photomultiplier module—and, due to the wide input range of 14 V to 23 V DC, the unit can be used with various types of DC input supplies.

Please note: There is a minimum order quantity of 20-off units, should this model not be in stock.
