Review: Great unit with only minor changes desired - I've got two of these chargers running 24/7. One has been running nearly constant since mid-June 2014 and the other has been in use since late April 2015. I'm also using the IQ4 controller to tie them together. These are used to run computer equipment tied to a large battery.(Currently, one unit is active at a time due to circuit limits on the 120v side. I swap them out about weekly.) These units have been running great. They run a pretty constant 45 amps without any problems. When the power goes out and runs down the battery, the chargers kick in with more amperage to run the equipment and charge the battery. My only wish is that the units came with lug terminals instead of screw terminals on the DC side. The screw terminals accept up to 4ga cable and, in my experience, the cable gets pretty warm when the device is operating fully. That's not the fault of the charger, but I would like to use larger cable. I also plan on buying more in the future, but it doesn't seem you can connect more than two units. *** Update 1/9/2017 *** I've been running these two chargers basically 24/7 since I got them. They are wonderful. Each device constantly runs between 30-40 amps DC output without a problem and when I disconnect one, the other easily takes over up to the maximum of 55 amps. I'm looking at either upgrading to the DLS-90 or adding an additional charger, but I still have my (apparently unique) situation of needing to connect more than two chargers to the IQ4, which does not appear to be possible. Review: Good rectifier! - Easy to install. Set output voltage of 13.5VDC. The max output current is rated at 55 amps. Simple plug in 120Vac input. Easy ground lead connection. Good rectifier, why buy anything else? ## Features - Quickly and effectively charges batteries - Designed to withstand low transient AC line voltage - Low operating temperature - Compatible with the IOTA IQ4 Charge Controller ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | IOTA | | Brand | IOTA Engineering | | Model | 0318.1402 | | Item Weight | 5 pounds | | Product Dimensions | 9.7 x 5 x 3.4 inches | | Item model number | 0318.1402 | | Batteries | 1 Unknown batteries required. | | Is Discontinued By Manufacturer | No | | Manufacturer Part Number | 0318.1402 | | OEM Part Number | DLS55 | | Special Features | Precise Output Control, Intelligent Charging | | Amperage | 55 Amps | | Voltage | 12 Volts | | Wattage | 781 watts | ## Images ![IOTA Engineering 318.1402 Converter and Charger, 55 - Amp , Black - Image 1](https://m.media-amazon.com/images/I/61pn4O-oCFL.jpg) ## Questions & Answers **Q: Will a 1000 watt generator power this charger without damaging it?** A: a generator listed as 1000 watt actually runs at a much lower production rate, more like 700 watts or so probably. always best to NOT stretch the generator, let it do the job easily rather than barely. electrical elements like this charger tend to have a SHORT life if voltage fluctuates/the juice gets thin. probably contact Iota tech support, their people are REALLY good, bright and helpful. batteries are expensive, most of the time even more than the generator and charger, so support your batteries for best cost-effective function **Q: Is the unit equipped with replacable fuses to protect it?** A: This unit does come equipped with two 30A fuses **Q: Does this unit include the IQ4?** A: This unit (at least the 55A version) does not come with the IQ4 charger. I just purchased it and had to get the IQ4 smart controller separate. The loop back cord the other answer was talking about was so you can quick charge at 14.2v instead of the normal 13.6v **Q: With a 270ah agm and 30a service which is often adapted down to 15a service, how do i know which size converter/charger to get?** A: What I use it for is battery power and charge power on a RV ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great unit with only minor changes desired *by N***L on May 26, 2015* I've got two of these chargers running 24/7.

Set output voltage of 13.5VDC. The max output current is rated at 55 amps. Simple plug in 120Vac input. Easy ground lead connection. Good rectifier, why buy anything else? ### ⭐⭐⭐⭐⭐ Works well as a Midtronics replacement! *by G***H on December 27, 2024* Have bought a few of these for battery voltage maintainer, used during vehicle module programming. Half the cost of the recommended factory maintainer. Just add about 5 feet of cable with ends from a decent set of jumper cables (one set of cables will make two). Good to go then. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/9561423-iota-engineering-318-1402-converter-and-charger-55-amp-black](https://www.desertcart.vu/products/9561423-iota-engineering-318-1402-converter-and-charger-55-amp-black) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-19*
