Compact solution for high power pulsed applications
ESP resistors from EBG provide a highly compact solution for high power, pulsed, low frequency applications such as:
- Inrush current limiting
- Capacitor pre-charge and discharge
- Motor control units
- Power supplies,
- Battery charging systems
- Inverter drives.
Right now, these resistors are popular in electric vehicle subsystems as pre-charge resistors and in-rush current limiting devices for industrial power control systems.
Large energy pulses
The special resistive element provides a highly reliable, non-inductive current path capable of handling large energy pulses up to 3300 joules over one second.
Small footprint
The EBG ESP resistor has a very small footprint when compared with thick film, ceramic and wire wound resistors with equivalent peak power ratings, an essential feature for applications where where space is very limited such as electric vehicles or military systems.
