DESCRIPTION

The SSR voltage regulator is completely solid state and uses

state-of-the-art circuitry to provide high performance with a wide

range of standard features. Voltage is internally or remotely

adjustable, with single- or three-phase customer selectable

sensing over a wide range. The SSR has a variable frequency

compensated operating characteristic (See Figures 1 and 2).

During start-up, the solid state voltage build-up circuit oper

ates from generator output residual voltages as low as 5%

of nominal. The built-in over-excitation limiting removes the

output power if the exciter field voltage exceeds a predeter

mined level. After removing field power, the regulator main

tains its shutdown state until the generator has decreased

below 5% of nominal.

The SSR may also be used with generator equipped with

single-phase permanent magnet generators (PMG) for ex

citation power. With this application or applications where a

power isolation transformer is incorporated, use suppression

chassis P/N 9261500100 or P/N 9261500101. supplied with

each regulator.

Maintenance of the SSR voltage regulator is simplified by the

use of replaceable modules. Sensitive electronic equipment

is protected from the effects of moisture, contaminants,

vibration, and shock, by encapsulation.
