・New Monitoring relay K8AK / K8DS series

The K8AK / K8DS series power supply monitoring relays detect
overcurrent/overvoltage, undercurrent/undervoltage, phase-loss^*1,
phase-sequence^*2, and voltage asymmetry^*3.


More expansion of business overseas in the manufacturing industry centering on
emerging countries and stronger needs for factory automation in emerging
markets demand responses to the following problems caused by the power supply
situation of devices and machines.
1.                    Malfunction of devices and machines caused by voltage
                       fluctuation due to unstable power conditions.
                       Motor error rotation caused by incorrect wiring of
                       power cable or motor burnout caused by loosened wiring
2.                     (disconnection) of power supply terminal part, which
                       comes from variation of proficiency for maintenance and
                       check.
                       Heating or troubles generated by inverter noise from
3.                     devices and machines when noise filter is not equipped
                       with the inverters.
                       

The newly released monitoring relays K8AK / K8DS series enhanced resistance to
inverter noise compared to our previous models. They suppress heating from the
monitoring relays themselves generated by inverter noise and monitor power
supply troubles even if the noise filter is not installed in the device or
machine. In particular, to prevent troubles including malfunction or motor
burnout coming from power supply error, the K8AK/K8DS series detect power
supply error (voltage or current), phase-loss, and phase-sequence. This
detection contributes to shortening recovery work and protecting the device
and machine quickly. The K8AK/K8DS series bodies are slim 17.5mm/22.5mm wide
and DIN Track mounting type, which conform to the global standard DIN48330.
These specifications contribute to downsizing devices and reducing the control
panel space.

*1. Phase-loss: The state in which voltage is not supplied to one or more
phases of three-phase power lines because of disconnection of power line,
loosened terminal screw, or contact failure of switches.
*2. Phase-sequence: The state in which phase sequence of three-phase power
line is not positive. For example, a motor rotates backward when the phase
sequence is reversed.
*3: Voltage asymmetry: The state in which power supply voltage of each
three-phase power line is not equal because of phase-loss or other reasons.


Features
   
     Wide range as a power supply monitoring relay for devices and machines
1.   (voltage asymmetry, phase-loss, phase-sequence, current, and
     temperature).

2.   It supports many power supply voltage and safety standards of the world
     (UL, CSA, CE, CCC, KC).

3.   17.5mm/22.5mm slim bodies conforming to DIN 43880 contribute to save
     space in control panels.

     Resistance to inverter noise is enhanced by redesign, suppressing heating
4.   generated by inverter noise when noise filter is not equipped for devises
     or machines.

5.   The K8AK/K8DS can be shipped from the OMRON factory with requested set
     values.
     * There are some conditions.
