The 2V16x Series relays are designed for the control of motor driven on-load power transformer tap changers. The 2V164-S Voltage Regulator Relay continuously monitors the transformer output voltage & current & provides “RAISE” & “LOWER” control commands to the on-load tap changer such that the load centre is automatically maintained within acceptable limits. Small variations in supply frequency will not affect the system performance. When designing the 2V164-S, considerable emphasis was placed on producing a relay which would be very simple to install, set up & operate in the field. The result is a simple yet effective & very dependable voltage regulator relay available at a competitive price. The relay is very easy to set up due to the large screen LCD HMI & PC programming port. RMS 2V164-S Relays have many in built features to simplify the interface with OLTC’s to provide a reliable, effective & simple to operate voltage control system.

Changes introduced on the 2V164-S

• Case length reduced by 18mm to suit 4M56-S case;

• LED backlighting to reduce EMC emissions – contrast adjustment no longer required;

• Front panel USB programming port to increase data transfer speed and improve compatibility with notebook PC’s;

• Network communications port is now optional to maintain low cost of base model;

• Network communication port maintained the optically isolated RS485 serial port but the RS232 configuration option has been deleted;

• New current and voltage channels to improve measurement stability;

• New status input option covering 18-275V AC and 300V DC range;

• Updated switchmode power supply to reduce EMC emissions and improve transient overload protection;

• Surface mount production technology to allow increased component density for additional functionality now and in the future.

What has not changed from the 2V164

• I/O and basic functionality has been maintained;

• Basic menu structure and operation has been maintained;

• Electrical terminal mapping has not changed allowing existing wiring diagrams to be maintained;

• Compatibility with existing application software back to version 0500 maintained;

• Compatibility with existing uMATRIXwin programming software maintained;

• Modbus RTU network communication protocol maintained Case size 4 has been maintained although the length has been reduced.

• Made in Australia
