AUTOMATIC VOLTAGE REGULATORS (AVR)

DLT SRV Servo Regulator​

30 kVA – 2000kVA

AUTOMATIC, CONTINUOUS STEPLESS VOLTAGE REGULATION

EXTRA WIDE INPUT VOLTAGE TOLERANCE

ULTRA PRECISE OUTPUT VOLTAGE ACCURACY

YEAR-ROUND PASSIVE SAVING CAPABILITIES

The servo system within the DELTA Servo Voltage Regulators provides the control of the DC motor with a thyristor.

Thanks to the booster transformer and variac (auto transformer) connected in series to the network, voltage regulation is made at the output. In this way, it provides a stable voltage at the output by preventing drops, rises and all other imbalances in the mains voltage.

CONSTANT VOLTAGE REGULATION, FROM NO-LOAD TO FULL-LOAD

Each voltage sensing module seamlessly and automatically controls each line of the 3-phase circuit independently to overcome the inherent voltage variations of the input power supply. This unique feature optimally regulates voltage anomalies to the desired output voltage level. Regardless of different voltage levels on each phase or imbalance of the load. automatically.

This unique feature ensures all voltage anomalies are optimally stabilised to your required output voltage value, no matter the difference in voltage levels, or load imbalance on each phase.

PROTECTION MADE PERFECT.

SWITCH ON YOUR SAFEGUARDS

AUTOMATIC FAILSAFE BYPASS CONTROL

To protect your load equipment from harmful high voltage, the AVR’s MBB Card senses for any abnormal signals, and upon detection, triggers the automatic failsafe bypass control switch to prevent damaging voltage from harming to your load equipment.

PUTTING YOU IN REMOTE CONTROL

ADAPTABLE VOLT-FREE REMOTE MONITORING

Dry Contacts (N.C & N.O) offers communication capabilities that alert you with signals of impending issues that need solving. This allows troubleshooting to be conducted ASAP, without interrupting your operations.

Whether it’s a visual flashing light on the front panel display of the unit, or an over-voltage alarm, the automatic voltage stabilizer’s Volt-free Remote Monitoring System triggers an appropriate response that allows you to get alerted—from the comfort of your control room.

ACHIEVE THE POWER TO PROTECT

OVER-UNDER VOLTAGE PROTECTION

Our over-under voltage protection safeguards your equipment from exceedingly high or low voltage fluctuations.

This defensive feature protects your load equipment from harm by triggering the automatic bypass control switch, preventing damage to both the AVR and your equipment.
