JUMO IPC 300 – Electronic Transformer (709051)
- Gentle mains operation under high-powered resistive loads (no flickering)
- Operation of low voltage heating elements directly at the supply network without adaptation transformer
- Minimal harmonics in the mains voltage of the device and low weight due to absence of a power transformer
- Short-circuit control during switch on process
- Mains current in proportion with the required power (amplitude control)
- Control is independent of the heating elements' resistive characteristics
- Reduction of the control reactive power
- Compact dimensions
- Free selection of the subordinate control loop U, U2, P, I, I2
- Compensation for the ageing process in SiC heating rods
- Heating element diagnosis
- Resistance limitation, protection of molybdenum disilicide heating elements against overheating in the upper temperature range
- Integrated semiconductor fuses to protect the IPC in the event of a ground fault
- Universally applicable for mains voltages up to AC 400 V
