GPS6-VA5 Self-Resetting Over/Under Voltage and Current Protector

The GPS6-VA5 self-resetting over/under voltage protector monitors voltage and current in a 2P AC 220V circuit. It combines adjustable overvoltage, undervoltage, and overcurrent protection with a dual LED display and automatic reconnection. Confirmed rated-current options are 40A, 63A, and 80A.

Working Principle

The microcontroller continuously compares the measured voltage and current with the selected protection limits. If a measured value moves outside those limits, the protector disconnects the output. After the supply returns to the permitted range and the configured delay elapses, the unit reconnects automatically. The supplied technical table lists a 0.5-second overvoltage trip delay.

Key Features

Overvoltage and undervoltage protection: adjustable limits allow the protector to respond to supply voltage outside the selected range.
Overcurrent protection: current monitoring adds another adjustable protection condition for the connected circuit.
Automatic reconnection: the output can be restored automatically after the measured values recover and the selected delay is completed.
Dual LED display: separate digital readouts provide clear operating information from the front of the device.
Front-panel adjustment: SET, up, and down buttons provide access to protection parameters and display modes.
Microcontroller-based control: the controller manages measurement, comparison, tripping, timing, and reconnection logic.
Panel-ready format: the 2P body supports DIN-rail mounting, and the front logo area can be customized where required.

Protection And Selection

Choose among the confirmed 40A, 63A, and 80A versions according to the circuit design, connected load, conductor capacity, and applicable installation requirements. All three listed variants use a 2P AC 220V configuration with an AC overvoltage setting range of 130-300V and an AC undervoltage setting range of 80-210V. Final selection should be checked by a qualified electrical professional.

Setting Instructions

Press and hold the SET button for five seconds to enter the setting state.
Use SET to move to the required overvoltage, undervoltage, current, or timing parameter.
Press the up or down button to change the displayed value.
Press SET to save the selected value. Refer to the product manual before changing protection settings in an energized installation.

Display Notes

Under DC power, the supplied instructions state that only voltage is displayed and current is not shown. Parameter P15 provides three display modes:

Mode 1 – Standard: displays parameters P1-P19.
Mode 2 – Manual: use the up or down button to view voltage (-U-), power (-P-), current (-A-), and frequency (-H-).
Mode 3 – Automatic: cycles through voltage, power, current, and frequency in sequence.

For parameter P19, the initial password is 112. If the lock parameter is changed and the password is reset, restore the parameter to 112 to unlock it.

Installation And Applications

GPS6-VA5 is designed for DIN-rail installation in compatible distribution assemblies that require monitored voltage and current protection. Before installation, confirm the AC 220V system, 2P wiring arrangement, rated current, conductor capacity, N/L terminal connection, protection settings, and local electrical requirements. Installation and parameter changes should be completed by qualified personnel with the circuit safely isolated.

FAQs

What is the GPS6-VA5 self-resetting voltage protector?

GPS6-VA5 is a 2P DIN-rail protector that monitors overvoltage, undervoltage, and overcurrent conditions. It can disconnect the output outside selected limits and reconnect after the supply recovers and the configured delay is completed.

How does automatic reconnection work?

The controller monitors the measured values after a protection trip. When the values return to the permitted range and the selected delay elapses, the protector restores the output automatically. The exact delay setting should follow the product manual and circuit requirements.

Which rated-current options are confirmed for GPS6-VA5?

The supplied SKU table confirms 40A, 63A, and 80A models, all in a 2P AC 220V configuration. Select the rated current only after checking the connected load, conductor capacity, circuit design, and applicable installation requirements.

What are the adjustable voltage ranges?

For the confirmed AC 220V models, the overvoltage setting range is AC 130-300V and the undervoltage setting range is AC 80-210V. The technical source also lists DC setting values, but no separate sellable DC SKU was supplied.

How are protection parameters and display modes adjusted?

Press and hold SET for five seconds, use SET to choose a parameter, adjust it with the up/down buttons, and press SET to save.

P15 selects Standard, Manual, or Automatic display behavior. P19 uses the initial password 112; consult the product instructions before changing lock settings.

What should be confirmed before installation or market-specific supply?

Confirm the 2P AC 220V system, rated current, N/L wiring, conductor capacity, DIN-rail space, protection settings, and local installation rules. Under DC power, the supplied instructions state that only voltage is displayed.
