Basler Electric SSR 125-12 SSR Series Voltage Regulator

DESCRIPTION

The Basler SSR Series Voltage Regulator precisely controls the output

voltage of an ac electric generating system by controlling the amount

of current supplied to the exciter (or generator) field. The SSR Series

Voltage Regulators are for use on brushless generators that require a

high performance regulator and use a wide range of accessory devices.

Compatible with a variety of input voltages and frequencies, the SSR

Series Voltage Regulator features a selectable V/Hz or 2-V/Hz frequency

characteristic. The 2-V/Hz characteristic is for improved prime mover

response during large motor starting and/or large load pick-up.

The greater voltage drop means less kW loading will be seen by the

prime mover and thus, a faster speed recovery.

Both the SSR 63-12 and SSR 125-12 have full-wave outputs, while the

SSR 32-12 has half-wave outputs.

ACCESSORIES

The SSR Series Voltage Regulators is designed to be compatible with any

of the Basler accessories and equipment listed below:

a. Remote mounted overexcitation circuit breaker (P/N 9185900014). 

Installation for more information.

b. Var/Power Factor Controller (SCP 250)

c. Series Boost Option (SBO 160)

d. Current Transformers (CT2 through CT50)

e. Exciter Diode Monitor (EDM 200)

f. Minimum/Maximum Excitation Limiter (EL 200)

g. Auto-Synchronizer (BE3-25A or BE1-25A)

h. Line Drop Compensator (LDC 300)

i. Manual Voltage Control (MVC 112)

j. Low and Medium Power Isolation Transformers.

SPIKE SUPPRESSION MODULE

Some higher impedance power sources (such as power isolation transformers

and PMGs) may have enough inductance to cause potentially damaging voltage

spikes in the power output stage of the SSR Voltage Regulator. In these cases,

Basler Electric recommends the use of the Spike Suppression Module which was

supplied with the Regulator to filter out these potentially damaging voltage spikes.

Refer to Section 2 for mounting and interconnection instructions.

Voltage Regulator Mounting

The Voltage Regulator will operate when mounted in any position, however, it 

should be vertically mounted to obtain optimum cooling. The Regulator can be

mounted in any location where the ambient temperature does not exceed the

operational limits. Due to its rugged construction, the Regulator can be mounted

directly on the generator. Mounting hardware should be selected based upon the

vibration and shock expected to be encountered during shipping/transport and

normal operation. Refer to Figure 2-1 for the outline drawing of the unit which

provides overall and mounting dimensions.

Spike Suppression Module Mounting

The Spike Suppression Module will operate when mounted in any position. The

Spike Suppression Module can be mounted in any location where the ambient

temperature does not exceed the operational limits.

Due to its rugged construction, the Spike Suppression Module can be mounted

directly on the generator. Mounting hardware should be selected based upon the

vibration and shock expected to be encountered during shipping/transport and

normal operation. Refer to Figure 2-2 for the outline drawing of the unit which

provides overall and mounting dimensions.
