1000W Switching Supply for Industrial Projects

This myVolts unit converts AC 100-120V or 200-240V input into adjustable DC output from 53V to 58V at up to 1000W. It suits CCTV installations, 3D printers, LED strips and custom computer projects that need a high-power DC source. Professional installation by a qualified electrician is recommended because no wiring, switch or mounting screws are included.

Sustained Load Behaviour and Protection

Efficiency exceeds 0.85 at 230VAC input and 25°C, and every unit passes a 100% full-load burn-in test. Overload protection triggers between 110% and 150% of rated power, shutting down the output until the fault clears and auto-recovery resumes operation. Short-circuit and over-voltage protections also guard connected equipment during continuous use.

Input Voltage Selection and Environmental Limits

A manual selector sets the supply for either 100-120VAC or 200-240VAC at 50-60Hz; the correct range must be chosen before powering on. The aluminium-cased unit operates from -20°C to +60°C at 20-90% RH and can be stored from -40°C to +85°C at 10-95% RH. CE and RoHS compliance is declared for the design.

Questions about this item

How much heat and noise should I expect when this 1000 W supply runs continuously at full load?

The unit is rated for 85 % input efficiency at 230 VAC and 25 °C, so roughly 150 W becomes heat. It uses a passively cooled aluminium case with no fan, so operation is silent but the enclosure will become hot.

What cables or connectors must I already have to wire this supply into my project?

You need suitably rated input wires for L and N, plus DC output cables for +V and -V. The supply ships without any wiring, on/off switch or mounting screws.

Will the adjustable ±2 V output let me match the 54 V rail on my older LED strips without modification?

Yes. The +V ADJ trimmer shifts the output between 53 V and 58 V, so you can set exactly 54 V to suit existing 54 V strips.
