APPLICATION:
The SSR Series Voltage Regulators provide reliable, high performance voltage regula-
tion 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 genera-
torline,orotherACsources.Suppliedwitheachregulatorisaspikesuppressionchassis
for PMG and power isolation transformer applications.
FEATURES:
• Regulation accuracy better than ±0.25%
• Adjustable frequency compensation
• 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 approved – CSA File Number LR 23131

SSR Series Voltage Regulators
2
TheSSRVoltageregulatoris completely solidstate 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-phase or three-phase cus-
tomer 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
operates 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 predetermined level. After removing field
power, the regulator maintains 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
excitation 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.
