Samlex Transfer Switch with Inverter Quick Connect 30 Amps - STS-30

The Samlex STS-30 transfer switch offers seamless power transitions between two separate AC input sources, ensuring you have a reliable energy source exactly when you need it. This intelligent switch can connect your utility power to a generator or inverter, making it an ideal choice for home backup systems and off-grid applications. With a rated capacity of 30 Amps at 120 VAC, this transfer switch is designed to meet the demands of modern power needs while enhancing the overall efficiency of your power management system.

Product Features

Automatic Source Switching

The STS-30 features automatic switching between utility power and generator, inverter, or between generator and inverter. This flexibility makes it easy to maintain continuous power without manual intervention, providing peace of mind to users during outages.

Heavy-Duty Relay Design

Equipped with a robust Double Pole Double Throw (DPDT) relay, the Samlex STS-30 ensures efficient switching of both the line and neutral connections. This design enhances durability and reliability, catering to heavy use and reducing the risk of failure.

DIP Switch Delay Control

With the integrated DIP switch, users can enable a time delay of 20 to 25 seconds when switching to generator power. This feature safeguards your equipment by allowing generators to reach stable operation before load transfer, preventing potential damage from sudden power surges.

Convenient Power Connection

The transfer switch comes with a standard North American power cord, allowing simple connection to 15 Amp NEMA5-15R receptacles on generators or inverters with an 1800 VA capacity. For full 30 Amp capacity, users can easily replace the cord with a larger one if needed.

Compact and Lightweight Design

Weighing only 4.4 lbs (2.0 kg) and featuring compact dimensions (8.4 x 9.0 x 3.2 inches), the STS-30 can be conveniently mounted without taking up excessive space. This makes it suitable for various installation locations, maintaining clean aesthetics while providing powerful performance.

How It Works

The Samlex STS-30 operates by seamlessly switching between two AC input sources, ensuring reliable power delivery to the household or equipment. With easy installation on either the line side of a main breaker panel or the load side to only switch dedicated circuits, the transfer switch is designed for versatility and practicality.

Input and Output Voltage Control

The device supports a steady input/output voltage of 120 VAC at 60 Hz, maintaining stable energy delivery for various types of electrical needs.

Operational Temperature Range

Built to operate efficiently within a temperature range of 0 - 40°C (32 - 104°F), the STS-30 functions reliably in a variety of environments, making it suitable for both residential and commercial applications.

Integrated Battery Charger Receptacle

Featuring a NEMA5-20R Duplex receptacle, this transfer switch allows for easy connection of battery chargers with a max of 20A and 16A continuous output. This adds an extra layer of utility and convenience for users who need to maintain battery systems.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric Supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Brian H

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go. Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
