A rectifier made for your line

Built to your plant's voltage

Built around your supply and your process.
Designed to run 24/7

A compact design meant for continuous duty, with the entire rectifier built in Mexico.
Forced-air cooling

A forced-air cooling system that keeps the unit running at its best, without interruption.
Protected equipment

Protection against overcurrent, over-temperature and swings in the incoming supply.
Direct delivery and support

Short lead times and technical support on the rectifier from the manufacturer itself.

Inside the cabinet: transformer, centrifugal fan, capacitors and in-house control boards mounted on a backplate, with the wiring run in trunking.

Control panel of a Meyse unit: digital voltage and current displays, voltage and ramp control knobs, timer and signal tower.

Control rail inside the cabinet: three-phase circuit breaker, power contactor and auxiliary relay, each with its identification label.

Direct current output busbars, marked + and −, bolted to the power modules and wired to the process with cable sized for the load.

Centrifugal fan of the cabinet, with its supply wiring landed on terminals.

Start and stop pushbuttons and signal tower mounted on the frame of a unit, ready to operate the line.

We build the entire electronic system, with our own control boards.

Precise control for an even coating

Controlling voltage and current is what gives you a consistent coating and an even quality of paint.

Programmable ramp

Purpose-built design that makes the voltage ramp easy to program for a quality coating.
Voltage and current control

High-precision control of the output current for a consistent coating.
Low ripple voltage

DC supply with constant filtering, so it works across different paint application ranges.
Equipment monitoring

Temperature control plus monitoring of voltage and of variations in the incoming supply.
Alarm and automatic operation

Alarm controller for the shutdown system, and electronics for automatic operation.
PLC integration

Optional PLC interface to control the output parameters on automated lines.

Chart from a real application: the voltage rises gradually from zero to around 260 V over some 160 seconds and then drops as the cycle ends. The lower curves, on the right-hand axis, track the bath temperature. — The voltage rises gradually, on a programmable ramp, up to the working value, and holds steady throughout the application on batch lines, with an adaptation for continuous lines.

About us

We build the whole system

At Meyse we build, modernize, repair and maintain rectifiers for electrodeposition processes. Every unit is designed around the line it will run on and the power available at the plant.

We build the entire electronic system: our control boards are our own design and most of them are compatible with commercial brands.
