All parameters are specified at 24Vdc input voltage, 8x5A output currents, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
Output voltage nom. DC 24V The output voltage is equal to the input voltage
minus the voltage drop of the module.
Voltage drop per channel typ. 125mV For CH1 or CH2 at 10A load when all other channels
are not loaded
typ. 190mV For CH1 or CH2 when all channels are loaded with
5A
typ. 165mV For CH3 to CH8 at 10A load when all other channels
are not loaded
typ. 210mV For CH3 to CH8 when all channels are loaded with
5A
max. 40A Below +60°C ambientSum current for all channels
max. 30A At +70°C ambient
nom. 1/2/3/4/6/8/10/12A For CH1 and CH2Current settings per channel
nom. 1/2/3/4/6/8/10A For CH3 to CH8
Factory setting 1A For all channels
typ. 200% For CH1 and CH2 in 1A settingCurrent limitation
typ. 150% For CH1 and CH2 in 2A to 8A settings
typ. 130% For CH1 and CH2 in 10A and 12A settings
typ. 50A For CH3 to CH8, independent of the settings
Channels 1 and 2 have a current limited output, while channels 3 to 8 have
an overcurrent shutdown behaviour only.
Load capacitance capability max. 100mF For CH1 and CH2 per channel
max. 20mF For CH3 to CH8 per channel
Output leakage current max. 2mA Per channel, when CH1 and CH2 are switched off
typ. 1.2mA Per channel, when CH1 and CH2 are switched off
max. 50μA Per channel, when CH3 to CH8 are switched off
Turn-on delay of outputs typ. 750ms Period between applying the input voltage and
turning on all output channels.
Tab. 5-1: Output data
Do not load the individual channels with higher average currents depending on the ambient temperature. Examples of
