Wieland P3-L, P3-LTN relays provide voltage control for three-phase power systems

Thursday January 26, 2017
Jan. 27, 2017 - Wieland Electric has expanded its flare Control series of phase control relays with two new modules designed to provide phase and voltage control functions for three-phase power systems in industrial applications.

The flare Control P3-L module provides basic phase control (phase sequence, phase position, and phase failure) for voltages from 200 to 500VAC, while the flare Control P3-LTN module boasts advanced control functions, including voltage balance, adjustable time delays, and overvoltage/undervoltage monitoring, as well as accommodates four-wire, three phase systems with a neutral connection. Both modules feature one changeover contact, in addition to multiple LEDs for monitoring and diagnostics. Wieland’s flare Control P3-L and P3-LTN phase control relays are housed in 22.5-mm wide DIN rail modules, and feature screw connections and both cURus and CE approvals. The operating temperature for the series spans -20 C to 60 C.
