Product description
This is a high-precision 4Q controller with a linear output stage, compact design with cooling on a heat sink which gives off heat to the exterior; output power from 10 watts to 1600 watts.
The DCE series can also be used as a controllable current or voltage source or a servo controller like the smaller devices in the DCP series but without their own power supply and fan as a 3HE plug-in version.
Adjustable +/- continuous and peak currents
Standardised types of current limitation:
A:
without peak current
B: 3-fold peak current over 50ms
C: 2-fold peak current over 200ms
4-pole measuring shunt connections for highly accurate bipolar current sources.
Monitoring of fuses, supply voltages and heat sink temperature.
Connector used: D, E or F in accordance with DIN 41.612 Special versions available by arrangement. |
