Gen4 Main Console 60A Max


The EMP4 is the largest Main Console in Gen4 series, equipped with dual ATmega328 microcontroller via 2x onboard Arduino Promini module. Basic hardware configuration using 180325 PCB has 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), 3x Hi-side, 3x Lo-side MOSFET Drivers, Logic I/O includes EDM probe sensing, 12V/24V Stepping Motor interface, key switch inputs, Top/Bottom/End position detect and LED indicator drivers which all controls via firmware and highly customizable.
The EMP4 has 2x side mounts 480W/720W LED Strip power supply and 4x 15A limited PWM output circuit that provides up to 60A at 24VDC of the continue output power (depend on in use PS rating). Additional power obtains via Expansion Console EXP4, Cascade Console ECP4 as desired.
Distilled Water were use as EDM dielectric fluid bath between Probe and work piece.
