Transformer Rectifier Assemblies
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.

Megohmmeter
1864-9700
The GenRad 1864 Megohmmeter is the choice for more demanding applications. The test voltage can be set to any value from 10VDC to 109VDC in 1-volt steps and to 1090VDC in 10 volt steps. Thus the GenRad 1864 can be set to any common, or uncommon test voltage for ceramic, mica or paper capacitors, or other devices. The reverse resistance of rectifiers can be readily measured; the low test voltages are especially useful in measuring solid state diodes. An additional range on the 1864 Megohmmeter permits measurements up to 200 T (2 x 1014)
