AC & DC SCR Module 0521-2500-00, 0522-2400-21 – New

*Can offer rebuilt modules as well for half the price.

AC CONTROL MODULE SPECIFICATIONS:
0521-2500-00, 2221-2500-00, EL22-2400-21
Input Supply: 115VAC, 6Ø, 60 Hz, 0.6A
Electronic throttle control via 0‐200mA signal to perform the following:
Regulation: 0.5 Hz, steady state
Response Time: 1 sec.
Load Unbalance: ± 5% of rated load, ±10% no load to full load, if one engine is cold
Electronic Generator Voltage Regulator performs the following:
Regulation: ± 3% maximum
Response Time: 1 sec.
Load Unbalance: ±10%, no load to full load of rated KVAR’s
KVA’s are distributed among generators by reactive droop compensation.
The module is constructed from 12‐gauge, cold‐rolled steel, and has its own heat sink.
Size: 14”L x 7.75”W x 11.5”D
Weight: 22 lbs.
HS CODE: 8537109090

Input Supply: 12VAC, 6Ø, 60 Hz, 0.6A
• 6 pulse thyristor firing circuits with “hard firing” outputs. The synchronizing signal originates
directly from the AC line.
• High speed current regulators with twenty millisecond response.
• Individual control of current limit for all drilling functions. The operator adjustable rotary
torque limit potentiometer will be mounted in the driller’s console.
• Motor speed regulators for the mud pump and draw works. Each regulator will be interlocked
with its related assignment contactor.
• Manual voltage control for maintenance operation.
• Thyristor gate suppression at approximately 150% of the bridge rating.
• “Zero Throttle Interlock”, the throttle on the drillers console must be returned to zero after an
assignment change before the motor can be powered.
• Module Fault Finder includes a meter and a switch mounted on the front of the module for
monitoring all critical internal voltages.
The module is constructed from 12‐gauge, cold‐rolled steel, and has its own heat sink.
