SSC63-4A (A.V.R)
110 / 220 VAC 50/60HZ OUTPUT : 63VDC 4A INTRODUCTION
The SSC63-4A Voltage Regulators are designed for use on 50/60 Hz brushless generators. The regulator includes frequency compensation, overexcitation shutdown, a solid-state build-up circuit, and EMIfiltering.
ELECTRICAL SPECIFICATIONS Dc Output Power :
4 Adc at 63 Vdc (252W) maximum continuous, 7 Adc at 100 Vdc (700W) forcing one minute (at 120 Vac input). 9 Adc at 134 Vdc (1206W) forcing for 10 seconds (at 153 Vac input).

NOTE
Fuse must be installed per the interconnection diagrams to avoid interrupting field current.

OVEREXCITATION SHUTDOWN
Overexcitation shutdown is included that removes the output power if the exciter field voltage exceeds 95 Vdc. If exciter field voltage exceeds 95 Vdc ±5%, the regulator automatically removes field current, after a time delay. The time delay is inversely proportional to the magnitude of the detected overvoltagecondition. At 134 Vdc, the field voltage is removed after approximately 10 seconds. Refer to the following figure.

Overexcitation Shutdown :
Field voltage shuts down after time delay if exciter field voltage exceeds 95 Vdc, ±5% (See Overexcitation Shutdown for inverse time delay curve and description).

Voltage Build-up :

V/Hz “CORNER FREQUENCY” SELECTION AND ADJUSTMENT
For 60 Hz systems, the regulator is preset at the factory for a 55 Hz “corner frequency”. For 50 Hz systems, a 45 Hz “corner frequency” is achieved by connecting a jumper across terminals Hz1 and Hz2. The cornerfrequency can be adjusted by the UF ADJ rheostat on the AVR. Clockwise rotation results in raising the corner frequency (shitting the curve to the right). To set the UF rheostat :

EXCITER FIELD VOLTAGE (VOLTS)

Typical Time Delay Characteristic Curves After output power is removed, the regulator can be reset by decreasing the input voltage to less than 6 Vac for a minimum of 2 seconds; thismay be accomplished by stopping the prime mover or by interrupting the regulator input with a reset switch.

FUSES :
Although the SSC63-4A has an internal fuse, it is recommended that fuses with high interruption capability be installed per the interconnection diagram to protect wiring form faults before the regulator. A spare fuse is included with the SSC63-4A (internal fuse). It is mounted...
