No ’sticking’ as can occur with fold-back characteristics. • Even longer overload possible as unit does not switch off.

The corresponding ground is the pole. Do not interconnect the "Signal GND" outputs. Exact output voltage regulation is effective when the output current is greater than 0.4A. Current sharing also works reliable with decoupling diodes and modules for redundancy applications. Vout=28V, Single Mode 0 Efficiency [%] ’Thermal Alarm’: warning signal at over-temperature • Signal: High (24 V) at correct operation (no over-temperature). If signal switches to ’low’ and temperature increases further, output current is lowered, • Ground and permissable load resistance: see ’Power Good’ output Vout=24V, Parallel Mode 8 4 ’Power Good’: Power-Fail / -Good • Signal: High (24 V) at correct operation (no overload, over-temp., short-circuit). At ’low’ signal and nominal load, output remains at nominal voltage for at least 5 ms. • Corresponding ground is ’Signal GND’ output (current source) • Permissable load resistance: ≥ 300 Ω, e.g. 24V relais, control lamp (no dropping resistor needed for LED), scoring logic. To get 5V level: connect this output and ’Signal GND’ via 5V zener diode (0.5W) + 1kΩ resistor switched in parallel Vout=24V, Single Mode 12 Output for measurements and signalling ’Shut-Down’: Shut-down input: units switches off, if • Input is connected to ’Signal GND’ (∆U < 1V) or • +20...28 V Voltage are applied to this input and ’Signal GND’ (max. 20 mA).
