Features:
- Adjustable Start-up/Delay Timer
Field-adjustable 0-15 seconds to avoid
nuisance alarms.
- Universal Outputs
Solid-state N.O. or N.C. contacts work on AC or DC up to 240V.
- Constant Hysteresis, Linear Setpoint Adjustment
Improves ease of use, responsiveness and accuracy to setpoint.
- Ease of Installation and Agency Approved
Self-powered, split-core cases available, and easily adjustable setpoint provide for quick and cost-effective installation. UL 508 (Industrial Control Equipment) pending.
Applications:
- Pump Motor Protection
- Electronic proof-of-flow. Senses motor current changes when pump runs dry, helping protect against bearing seizure or burn out.
- Non-intrusive, less expensive and easier to install than differential pressure flow switches or thermal switches.
- High Inrush or Short Overload Currents
Adjustable start-up/delay timer allows 0-15 second delay to eliminate nuisance trips from high inrush or short overload conditions.
