A voltage event rarely announces itself. It’s often a quiet moment: lights flicker once, a motor sounds slightly strained, a control board reboots, and the day’s work suddenly becomes troubleshooting. This DIN Rail Adjustable Over/Under Voltage Protector Relay is designed for that exact reality—when you need protection that reacts faster than a human can, but remains simple enough to set up on the first visit.
In a panel, the unit presents a clean, compact face with dual LED digits that stay readable even under harsh utility-room lighting. Instead of guessing whether the supply is “probably fine,” you can see voltage/energy information immediately and confirm whether the line is drifting. When the incoming voltage crosses your configured threshold, the relay disconnects the load to reduce the chance of insulation stress, overheating, nuisance resets, or premature failure in sensitive electronics.
After the grid stabilizes, the device’s reconnect delay prevents rapid cycling—so compressors, pumps, and power supplies aren’t hammered by repeated restarts. The result is a calmer system: fewer unexplained shutdowns, fewer burnt components, and fewer urgent call-backs caused by power quality you can’t control.
This device is capable of monitoring the incoming voltage and disconnecting the load when the voltage exceeds or drops below a certain threshold, esuring that the connected devices are safe from overvoltage or under voltage conditions.

Overvoltage protection (>U)
Adjustable from 230V to 300V to help match local grid behavior and the tolerance of your connected loads.
Undervoltage protection (<U)
Adjustable from 210V down to 140V to help prevent brownout stress—often the hidden cause of overheating motors and unstable power supplies.
Trip behavior
0.5s trip delay supports decisive cut-off when thresholds are exceeded.
Reconnect logic
5–90 seconds (default 30s) helps avoid “chatter” during unstable recovery.
Up to 600 seconds start delay supports systems that need longer stabilization or compressor equalization time.
Practical outcome: instead of repeated micro-outages damaging equipment over weeks, the protection strategy reduces cumulative stress in a way you can verify and tune.
A protection device is only as trustworthy as your ability to verify it. The dual LED display provides direct, “walk-up readable” feedback—useful in tight panels where a phone flashlight and a rushed inspection are the norm. The metering elements (including 0–99999.9 kWh display capacity and 1200 imp/kWh pulse frequency) support routine checks and help confirm whether the line behavior matches what operators report.
Accuracy matters in troubleshooting. The listed accuracy (Level 1 and 2% of overall range) provides a practical balance: stable enough for field verification, simple enough to maintain, and clear enough to spot abnormal drift without adding a separate measuring instrument every time.
Mounting: snaps onto 35mm DIN rail, keeping wiring aligned with common distribution board layouts.
Space discipline: the device is shaped for compact panel organization; keep adequate ventilation and cable bend radius.
Commissioning checklist
Confirm incoming supply is within the unit’s operating voltage range (AC 85–350V).
Set over/under thresholds according to the tolerance of the downstream load.
Select a reconnect delay that prevents rapid cycling (especially for motors and compressors).
Verify display readings during a controlled power-up before leaving site.
Tip from field practice: if a site experiences frequent voltage dips, increasing the reconnect delay can reduce repeated restarts that quietly shorten equipment life.
Residential distribution boards protecting appliances sensitive to brownouts (refrigerators, HVAC controllers, electronics).
Light commercial loads where nuisance shutdowns create downtime and service costs.
Workshops and small machines exposed to line instability from shared feeders, welding equipment, or generator changeover.
Remote or rural supply lines where voltage swings are more common and long cable runs increase fluctuation.
What changes for the user: fewer “mystery failures,” fewer scorched power supplies, fewer intermittent faults, and a more predictable daily operation.
Electrical cabinets can run hot, dusty, and cramped. The ABS enclosure provides an insulating, durable shell that feels solid in hand and resists the scuffs and tool knocks typical during installation. The wide stated temperature ranges (ambient -45°C to 75°C, operating -50°C to 55°C) indicate suitability for varied climates and cabinet conditions—helpful for projects that move between regions.
Combined with configurable delays and thresholds, the unit aims to remain stable in the real world: unstable grids, frequent switching events, and the “always on” rhythm of distribution equipment.
Specification-driven documentation: we keep the key parameters explicit—threshold ranges, delay windows, accuracy, metering pulse—so your selection is based on numbers, not vague claims.
Consistency for panel builders: DIN-rail format, readable display, and clear setting ranges simplify assembly and commissioning across multiple projects.
Support that matches field reality: configuration questions usually happen on-site; our team can help align threshold and delay settings with typical load behavior.
Manufacturing experience: established operations (founded in 2003 per provided company info) support stable supply and ongoing product iteration.
1) How do I choose the right over/under voltage settings?
Start with the tolerance of the downstream equipment. Set overvoltage within 230–300V and undervoltage within 210–140V to avoid nuisance trips while still preventing harmful extremes. If the site has frequent dips, a slightly lower undervoltage threshold plus a longer reconnect delay often improves stability.
2) What reconnect delay should I use?
For general loads, 30 seconds (default) is a practical baseline. For compressors, pumps, or systems prone to repeated restarts, consider increasing within 5–90s or using the extended 1–600s start delay to avoid rapid cycling.
3) Is this device only for 230V?
It is designed for AC220V / 230V class single-phase systems, with an operating voltage range of AC 85–350V. Always confirm your application stays within the specified range.
4) What does the dual LED display show?
It provides on-device visibility of operating information. The unit also supports energy/power monitoring with a 0–99999.9 kWh display range and 1200 imp/kWh pulse frequency.
5) Does it include leakage protection?
Yes, it lists electric leakage protection adjustable from 10–99 mA. Ensure your overall protection scheme and local codes are followed when setting leakage thresholds.
6) Can I mount it in any distribution box?
It mounts on a 35mm DIN rail. Ensure adequate clearance, ventilation, and correct conductor sizing for the 60A rated current.
