Three-Phase Rectifier Bridge 40A 1600V for Industrial Applications
Efficiently converts three-phase alternating current into direct current to power industrial equipment, welding systems, or renewable energy installations. This SQL-4016 model supports loads up to 40A and voltages of 1600V, designed for continuous operation in demanding conditions. Integrated aluminum heatsink for optimal thermal dissipation and long-term reliability.
What you get with this product
- Stable AC-DC conversion for continuous power supply to motors and industrial equipment without voltage fluctuations
- High current capacity of 40A allows direct connection of powerful consumers without the need for additional rectifiers
- Robust aluminum casing with integrated heatsinks ensures efficient passive cooling and eliminates the need for external fans
- Resistance to inverse voltages up to 1600V protects the installation against overvoltages and network surges
- Faston terminal connectors facilitate quick assembly and ensure secure electrical contacts without the need for special tools
- Compact design 9.8 x 6 x 5.3 cm allows installation in standard electrical panels or on DIN rails
How it works and how to install
The rectifier bridge uses six diodes configured to take the three phases of alternating current and convert them into a pulsating DC voltage at the output. The terminals are clearly marked on the casing according to the electrical diagram: three inputs for AC phases and two outputs for positive and negative DC. Installation is done by mounting it on a metal surface for additional heat dissipation and connecting the conductors to the corresponding terminals, observing the indicated polarity. The finned heatsinks dissipate heat through natural convection, without moving parts.
Frequently Asked Questions
Is forced fan cooling necessary for continuous operation at 40A?
No, the integrated aluminum heatsink provides sufficient thermal dissipation through natural convection for operation at nominal current, provided it is mounted on a metal surface for additional heat evacuation.
Can I connect the bridge directly to a 380V three-phase network?
Yes, the bridge supports standard industrial three-phase input voltages, but the DC output voltage will be proportional to the RMS value of the AC input, reaching approximately 540V DC for 380V AC three-phase.
What cable cross-section is recommended for connecting the terminals at 40A?
For a nominal current of 40A, cables with a minimum cross-section of 6 mm² copper are recommended, ensuring a thermal safety margin and limiting ohmic losses on the conductors.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
