Basler Electric Class 200 Equipment SSR Series Voltage Regulators

The SSR Series Voltage Regulators provide reliable, high performance voltage regu

lation for 50/60 and 400 Hz brushless generators requiring 12A of excitation at either

32. 63 or 125 Vdc. The SSR Voltage Regulator receives its power for precise voltage

regulation from a PMG (Permanent Magnet Generator), self excitation from the gen

erator line, or other AC sources. Supplied with each regulator is a spike suppression

chassis for PMG and power isolation transformer applications.

FEATURES

• Selectable single or three-phase sensing

• Built-in parallel droop or cross current compensation

• Overexcitation shutdown

• Solid state voltage buildup

• EMI suppression built-in

• Modular replaceable parts for ease of service

• Applicable for 50. 60 or 400 Hz systems

• Compatible with single phase PMG generator

(50 to 240 Hz power input range)

• Spike suppression chassis

• Compatible with a wide range of accessory control and

protective devices

• CSA certified, CSA File Number LR 23131

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.
