The Posmith 63A Digital Voltage Protector is an essential "watchdog" for your electrical system, designed to shield your entire home or workshop from unpredictable power grid fluctuations. At Electrapac, we recommend this DIN-rail mounted protector for its 3-in-1 capability: it monitors Over-Voltage, Under-Voltage, and Over-Current in real-time, automatically disconnecting the load to prevent catastrophic appliance failure.

Product Overview

The Posmith protector acts as an intelligent circuit breaker. Unlike standard breakers that only trip during a short circuit, this device detects subtle but dangerous voltage spikes (from lightning or grid switching) and brownouts (low voltage that can burn out refrigerator motors). Once the grid stabilizes, the device features an adjustable Auto-Recovery timer to safely reconnect your power.

Key Features for Electrapac Customers

• Dual Digital Display: Provides a simultaneous readout of your current Voltage (V) and Current (A). It doubles as a digital panel meter for your main distribution board.

• Fully Customizable Thresholds: Every home has different needs. You can manually set exactly at what voltage the power should cut off and how long the device should wait before turning back on.

• High-Speed Trigger: Features a lightning-fast response time (< 0.1s), ensuring that high-voltage surges are blocked before they reach your sensitive electronics.

• Automatic Recovery: You don't need to manually flip a switch after a power trip. Once the voltage returns to a safe range, the Posmith protector restores power automatically after your pre-set delay.

• Over-Current Limiting: Protects your internal wiring by allowing you to set a custom current limit (setting it to 30A even if the device is capable of 63A).

Installation & Wiring Guide

The Posmith protector is designed for easy integration into standard consumer units (DB boxes).

1. Input (TOP): Connect the "Line" (L) and "Neutral" (N) from your main energy meter to the top terminals.

2. Output (BOTTOM): Connect the bottom terminals to your internal circuit breakers or loads.

3. Programming: Use the "Set" button to toggle through Under-Voltage, Over-Voltage, and Current settings. Use the Up/Down arrows to adjust the values.

Electrapac Safety Tip: Even though this device is rated for 63A, ensure your input cables are of sufficient thickness (10mm2 or 16mm^2) to handle the total load of your premises safely.

Primary Applications

• Whole-House Protection: Installing at the main entry point to protect ACs, fridges, and TVs from grid instability.

• Industrial Machinery: Protecting expensive CNC machines or motors that are sensitive to "phase brownouts."

• Server Rooms: Ensuring that IT equipment is never exposed to high-voltage surges.

• Solar Inverter Outlets: Monitoring the output of off-grid inverters to ensure stable 220V delivery.
