Three-phase rectifier bridge 20A 1200V for industrial AC-DC conversion
Efficiently converts three-phase alternating current into direct current for industrial applications and power equipment. The SQLF-2012 rectifier bridge is a robust solution for powering DC motors, welding systems, or electroplating installations that require stable conversion at voltages up to 1200V and loads of 20A.
What you get with this product
- Stable AC-DC conversion for industrial equipment — supports operating voltages up to 1200V and direct current of 20A
- Efficient thermal dissipation via integrated aluminum heatsink — maintains optimal operating temperature without the need for forced ventilation
- Robust aluminum housing with 5 connection terminals — ensures quick mounting and secure electrical connections in control panels
- Universal compatibility with industrial three-phase systems — suitable for DC motors, power supplies, welding equipment, and galvanic installations
- Integrated protection through power diodes — blocks reverse current and ensures safe operation under variable load conditions
- Compact dimensions 60 x 35 x 40 mm — easily integrates into small spaces in electrical cabinets or distribution panels
How it works and how to install
The rectifier bridge receives three-phase alternating current through its three input terminals and converts it into direct current at the output using a power diode configuration. The six diodes allow current to flow only in the required direction, generating a pulsating DC voltage that can be filtered for sensitive applications. The aluminum heatsink dissipates the heat generated during operation, ensuring thermal stability.
Installation is done by securing the component to a flat surface or DIN rail in the electrical panel, connecting the three AC phases to the input terminals and connecting the DC load to the positive and negative output terminals. It is recommended to use appropriate fuses on each phase and to check the connections before commissioning.
Frequently asked questions
Can it be used to power a 2kW DC motor?
Yes, the bridge supports 20A at 1200V, making it suitable for medium-power DC motors in industrial applications, provided that the motor's voltage and current are within the specified limits.
Does it need additional heatsink or forced ventilation?
No, the integrated aluminum heatsink is sufficient for thermal dissipation under normal loads. If it operates continuously at maximum current, mounting it in a ventilated space is recommended.
What type of protection should I add to the installation?
It is recommended to install fuses or circuit breakers on each input phase, sized for the working current, plus a capacitive filter at the output to smooth the DC voltage if the application requires high stability.
