NK Technologies ASX Series AC Current Operated Switches with Time Delay
The 'ASX' Series from NK Technologies is a high-performance current-operated switch with field-adjustable time delay to help minimize nuisance trips during start-up and operation. Designed for motor status applications where setpoint accuracy and repeatability are critical, the ASX offers a linear setpoint characteristic and constant hysteresis. Standard features include self-powering, jumper-selectable ranges and a choice of outputs and cases.
Applications
- Motor Protection
Serves as an electronic proof-of-operation; detects current draw changes in motors when they encounter problems such as pumps running dry or pending bearing failure.
Non-intrusive, less expensive to install than differential pressure flow sensors or thermal switches. Much quicker response time than Class 10 overload relays.
- High Inrush or Temporary Overload Current
Adjustable start-up/delay timer allows 0-15 second delay to eliminate nuisance trips from highinrush or short overload conditions.
Features:
- Adjustable Start-up/Delay Timer
Field-adjustable from 0-15 seconds to eliminate nuisance alarms due to start-up inrush or temporary overcurrent conditions.
- Choice of N.O./N.C. AC or Universal Outputs
Contact ratings of 1.0A@240VAC or universal outputs of 0.15A@240VAC/VDC (N.O. models and 0.2A@135VAC/VDC (N.C. models) for use with most standard motor control systems.
- Improved Ease of Installation and Use
- 1.0A rating eliminates need for time delay relay
- Self-powered, split-core models simplify installation
- Status LED provides visual indication of setpoint trip and contact action.
- Industrial Grade Performance
Constant hysteresis and linear response characteristic enhance accuracy to setpoint
- Agency Approved
UL, CE approvals pending
