## Overview

The GamaTech 220V 145PSI Pressure Switch is a digitally adjustable, durable pressure controller designed for water and air pumps up to 1.5HP. Featuring a true 1/2 inch male NPT connector and an IP66 waterproof rating, it offers precise pressure management with automatic pump protection against dry-run damage. Ideal for US/Canada markets, it replaces unreliable mechanical switches with easy digital adjustments and a clear pressure display.

## Description

Technical specifications: Pressure range: 0 - 145 PSI, Power supply: 220V AC 50/60Hz, Max. current: 5A, Max. power: 1.1kW, Max. working fluid temperature: 175° F (80° C), Threaded connector size: 1/2 in NPT, Waterproof IP rating: IP66, Long service life: over 20 mil. start/stop cycles.

Review: Works great - Works great vs the mechanical ones that are so hard to adjust. Update after 11 months: I have 2 units one on the pump going to the house and the other for the sulf removal tank. The units worked great for about one year so far. The complete range pressure adjustment is great for the sulf tank pump as I can go down to 2 psi. I damaged one switch by installing it in short and it started to not shut off at right pressure. Purchased anther and no issues.
Review: Failed most important feature advertised - This “smart” controller implements faulty logic; has a low input pressure “shutdown “ feature meant to protect a secondary pump that draws water from a tank (aerator in my case). If tank runs dry due to primary circuit failure, controller is supposed to shutdown secondary pump. This controller, on detection of low pressure, shuts secondary pump off, but then periodically retries forever, or in my case, until it fried the secondary pump. Complete fail, cost me a $500 motor. Do not recommend.

## Features

- US/Canada Market Compatibility: Specifically designed with true 1/2 inch male NPT threaded connector and PSI units, serving as a reliable replacement for mechanical switches with springs. Compatible with well water pumps, submersible pumps, air compressors and other water and air pumps
- Automatic Dry Run Protection: Features an automatic shut-off function that stops the pump in case of well water shortage, preventing your pump from burning out when there is no more water at the source
- Direct Connection Capability: Works in straight connection with any pump up to 1.5HP (1.1kW). For pumps with higher power ratings, a relay must be used for proper operation
- User-Friendly Adjustable Settings: Adjustable high and low pressure settings as simple as pressing a button. The digital display shows the actual pressure in real-time, eliminating the need for additional pressure gauges
- Technical Specifications: 220V, 50/60Hz, 5A, 1.1kW, 0-145 PSI pressure range, 1/2 inch male NPT threaded connector, waterproof IP66 rating for reliable outdoor and indoor use

## Questions & Answers

**Q: The wires are very small gauge stranded copper. Is there over current protection inside this unit?  It goes on a 15 amp circuit.**
A: It is 220v, the higher the voltage the lower the current needed, therefore the amperage it uses and the size of wire. It is rated for 1500W. No problem for my 3/4hp pump, been working perfectly so far for months. I haven't found anything like this on the market and the mechanical ones went bad every year.

**Q: What is the Current rating?**
A: 1500 W about 6.5 Amps

**Q: What happens when there is a short circuit on the output side of the device? Does it fail safe or do the wires or the device itself start to burn?**
A: Breaker trips...

**Q: Length and gauge of leads?**
A: About 12" 16 gauge

### ⭐⭐⭐⭐⭐ Amazing upgrade
*by A***N on August 17, 2022*

Replaced my mechanical pressure switch on my submersible well pump. It’s a 1.5HP single phase pump with a control box. I just removed the old switch and installed this one on the same wires (2 wires for power IN and 2 wires for power “out” ) 10 minutes install BUT please note that because the thread on this switch is 1/2” and normally (mine was) mechanical pressure switches are 1/4” you will need to run to the hardware store and buy a reduction 1/2” x 1/4” (I found at ACE but Home Depot or any hardware store will probably have it). I also added a 90 degree elbow so the display will be facing up, easier to see You can easily adjust any pressure for “on & off” separately and so choose the differential you want - Mine is set to 55-70 psi There also a “Dry fault” protection: if pump runs dry (no pressure) due to no water on the well or a broken pipe the switch turns the pump off automatically and shows a LED alarm That’s exactly what I wanted! Note to the manufacturer: 1) You should offer option of 1/4” thread 2) Next step: why not a WiFi interface with an App that we can control the switch from any smartphone AND receive alerts like no pressure, overtime running, and maybe even a water consumption meter! I will pay good 💰💰💰💰 for something like that! Home automation is the future!
