ET System Bidirectional DC Sources

with GRID power recycling
From 30kW to 2MW
From 30 kW to 2 MW
Voltages of 5-300 V/ 5-600 V / 5-1,200V
Maximum currents in a single system ± 1,500 A
Available as multi-channel output (e.g. 2-channel DC output)
Continuous transition from charging to discharging
Modular system, systems can be connected in parallel
Galvanically isolated from the grid
TFT touch display with simple menu navigation
Emergency off in the front door
Indicator lights for operating status
Fast response time < 1.5 ms (optional < 3 ms)
Low grid feedback effect
Sens Connection for compensating voltage drops on the DC line
Programmable sequences that can be stored and reloaded
Voltage rise time and current rise time (U and I slopes) are adjustable
3 operating modes: constant voltage (CV), constant current (CC+ & CC-), constant power (CP+ & CP-) for charging and discharging
The systems’ “hardware limits” can be set specifically for the application
Standard interfaces: LAN and RS485 (CAN optional)
