Gen3 Main Console 15A


The EDMP3 equipped with dual ATmega328 microcontroller via 2x onboard Arduino Promini module. Basic hardware configuration using 171114 and 171107 PCB set provides dual 2004A I2C LCD (can add many in parallel as needs) port, multiple Temperature readout (Inner-Air, Heatsink) using DS18B20 Temp. Sensor, 2x DVM (Vin and Vprobe), 1x DAM (EDM Current), 1x PWM output (phase-correct 16-bit PWM 30~50K Hz 1~95% Duty), dual Hi/Lo side MOSFET Drivers, Logic I/O includes EDM probe sensing, 12V Stepping Motor interface, key switch inputs, Top/Bottom position detect and LED indicator drivers which all controls via firmware and highly customizable.
The EDMP3 top mounts 480W LED Strip power supply and single 15A limited PWM output circuit that provides up to 15A at 24VDC of the continue output power (depend on in use PS rating).
Distilled Water were use as EDM dielectric fluid bath between Probe and work piece.
