Tele Haase’s KAPPA series is a range of monitoring relays with plug-in socket assembly.
The recessed knobs prevent accidental adjustment and the LEDs are protected against electrostatic discharge, to deliver reliability and simple operation. The 11-pole plug-in socket is preferred for applications such as pre-fabrication or allowing units to be replaced while still live or enabling unskilled staff to replace units. The KAPPA range includes voltage and power sensor relays for use in single- and three-phase networks.
The K3YM400VSY20 is for monitoring the clockwise direction of rotation, monitoring mains symmetry, under-voltage and windows monitoring. Phase failures can also be recognised with the help of the device. Asymmetry that may be set from 5 to 30% allows such recognition to be set or deactivated depending on the mains environment. A delay may also be set from 0,1 to 10 seconds. The unit possesses two switch-over contacts as output so that malfunctions may be reported or direct switching actions may be set. The activated relay signals whether voltage, phase sequence and asymmetry are in order. In the event of malfunctions, the output relay will break contact after a short delay. The permissible switching thresholds (min. and max.) may be set between 70 and 120% of the rated voltage or between 80 and 130% of the rated voltage.
The K3PF400VSY02 is for monitoring mains symmetry and clockwise rotation; it will also recognise phase failures. It possesses two switch-over contacts as the output so that malfunctions may be reported or direct switching actions set. The activated relay signals whether the symmetry and phase sequence are in order. In the event of malfunctions, the output relay will break contact. The permissible asymmetry may be set between 5 and 25% depending on the mains environment. When necessary, asymmetry monitoring may also be deactivated, ie, when monitoring the direction of rotation only is required.
The two new K3UM230VAC02 and K3UM24VDC02 voltage monitoring relays permit single-phase loads to be monitored either with direct or alternating currents. The former works with a rated voltage of 230 V a.c. and the latter with a rated voltage of 24 V d.c. The two new types possess the already familiar functions for under-voltage and window monitoring. The fact that both units possess adjustable switching thresholds (min. and max.) means that defined deactivation or release points may be set by users. The minimum switching threshold may be set between 75 and 115% of the rated voltage and the maximum switching threshold between 80 and 120% of the rated voltage. As soon as the measured voltage falls below or exceeds the range defined by the user, the output relay will immediately break the contact and the corresponding LED will light up. Two change-over contacts, which indicate faults or execute direct switching activities, serve as the output.
The plug-in K3IM5AACL20 current-monitoring relay delivers a range of performance and covers a broad array of applications. The switching thresholds (min. and max.) for OVER, UNDER and WINDOW functions may be set from 0,25 to 5 A. In this version, these functions also possess an error memory that may be selected by rotary switch. The break delay allows the error signal through the change-over contacts to be delayed by between 0,1 and 10 seconds. In addition to the delay, the unit also possesses a start override, which may be set from 0 to 10 seconds. The unit possesses two switch-over contacts as the output so that malfunctions may be reported or direct switching actions may be initiated.
