download pdf file The PAHA & PAHI are 3 wire relays for sequence control and phase monitoring. The PAHI includes a true time delay. The PAMA&PAMI are 4 wire relays for sequence control and phase and neutral monitoring. The PAMI includes a true time delay.
download pdf file The phase failure relays are designed for application where a three-phase system needs to be monitored for unbalance or deviation in balanced voltage or deviation in frequency. the PADF offers seperate terminals for internal power.
download pdf file The phase failure relays are designed for applications where a three-phase system needs to be monitored for unbalance or deviation in balance voltage. The relays includes a standard timing function. In addition the PADI and PANI offers a true time delay on drop out even at total power failure. The relay works in "fail safe"mode and need no external power supply. If an external stable power supply is available the 45mm housing offers seperate terminals for internal power.
download pdf file The current relay is designed with a micro-controller.With programmable range, function and timing it can be programmed to cover all kinds of applications. The monitored current is fed through an internal shunt with a voltage is then amplified in a balanced amplifier, rectified, averaged and compared with a preset reference voltage.AC and DC current between 1 mA and 10A can be measured directly.By means of a current transformer or a shunt resistor the range can be extended without limits.
download pdf file The current relay is designed to cover all possible AC current monitoring and control applications-including differential current measuring (earth leakage)-in the range from 5mA to 100A. Higher sensitivity can be achieved by pulling the current carrying wire multiple times through the relay. The wide range, 4 decades, are divided into 12 sub ranges for easy adjusting.For an external monitoring of the actual input, there is a 20mA output signal related to the max. of the set range.
download pdf file The current relay is designed to be used as a trip relay in a 4 to 20mA current loop. The ILUA comes with single turn potentiometers for the set point an the different, and the ILUB with multi-turn potentiometers for precise setting. The differential is adjustable from 1 to 20% of the set tripping current. The relay is powered from an external 16 to 32 VDC source, and includes a 35mA current limits, a Red LED will be it and in case of with a common 0 to 2 sec. adjustable timer for pull in and drop out. The timer can as an option be specified up to 30 sec. and disabled for either pull in or drop Out delay.
