OLTC Position Monitor UP4x series
Description

UP3x series

OLTC UP3х series compatible with selsyn sensor:

• Compatible drives PDP-4, PDP-4U; МА-1, МАК-1 and any other drives equipped by sensors BD404 or BD1404 with number of taps not more than 99;
• Possibility to set initial angle of selsyn sensor when transformer is turned-on and fixed on a tap;
• Indication of first/last and boundary taps of drive position by means of LEDs;
• Analogue output “Current loop” (0-5mA, 0-20mA or 4-20mA) upon customer’s request.


UP Monitors family contains a number of devices, form very simple models suitable for solving particular problems to complex multifunctional devices that can be employed anywhere. Using our devices one can receive position information from any type of OLTC and transmit it via digital or analog outputs.

• Alarm of boundary, first and last taps of drive position (UP23, UP25, UP31 and UP41);
• Additional discrete outputs for signals about following events: first or last drive’s tap are reached, tap switching, reaching of boundary tap position (UP23, UP25, UP31 and UP41);
• Digital output RS-485 (RS-232), used by the MODBUS RTU/ASSII Protocol, allows you to transmit information about the position of the OLTC drive to SCADA and configure the device when connected to a computer;
• Additional analogue output “Current loop” (0-5mA, 0-20mA or 4-20mA) for transmission of information on drive to SCADA position (UP23, UP25, UP31 and UP41);
• Possibility to compensate electrical resistance of connecting wires and work in configuration mode when the transformer is turned-on and located in the fixed position on one tap (UP23 and UP25).

UP benefits:

• Wide Range of Products family — one can choose a device that exactly fits to his system or use the same universal modes for different situations;
• Wide range of input types — Synchro transmitter, Current loop output, Resistive sensor, BCD encoder, RS-485;
• Wide range of data outputs — RS-232, RS-485, Analog current loop, Relay outputs, Block output signal;
• Highly configurable;
• Alarm of boundary, first and last taps of drive position;
• Additional discrete outputs for alarms about following events: first or last drive’s tap are reached, tap switching, reaching of boundary tap position;
• Digital output RS-485 (RS-232) used by MODBUS RTU/ASСII protocol that allows transferring the information on position of OLTC’s drive to SCADA system and configuring the device from PC;
• Additional analogue output “Current loop” (for transmission of information on drive to SCADA).
