Tap sensor DP3 is designed to determine actual transformer tap on load. This sensor can be used with PDP1, PDP4, MA-1 and RNT-13 drives, as well as the other drives that can be completed with synchro transmitters (BD404 or BD1404) or other sensors with the dimensions of BD404/ BD1404 type sensors. Tap sensor DP3 is a metal cylinder with chamfers for installation needs. Overall dimensions and mounting points of DP3 type sensor are the same as those of BD404 or BD1404 synchro transmitters.

Sensor DP3 is a drive turn angle encoder with signal conversion circuit, it can be installed instead of a synchro transmitter. Sensor DP3 has several different interfaces in order to transmit the drive turn angle. These are: interface RS-485 for the transformer tap data transfer to PCS or to UP 25 OLTC Position Monitors in digital form via MODBUS protocol. Current analog interface “current loop” 4-20A, 0-5mA or 0-20mA is designed for the transformer tap data transferring to UP 25 OLTC Position Monitors or PCS by additional transmitters. Analog interface 0-5V or 0-24V for transformer tap data transfers to UP 25 or to PCS via additional transmitters.

While using this interface sensor DP3 can function as a resistive sensor of MZ-2, MZ-4, EM1, MR, and ED-S drives. In this case the sensor can be used to connect Siemens and ABB transformer protection and control automatics together with drives of PDP-1, PDP-4, MA-1, and RNT-13 types and others.
