Over-Current Protection
To provide protection in an output over load fault condition,
the unit is equipped with internal over-current protection.
When the over-current protection is triggered, the unit enters
hiccup mode.
The units operate normally once the fault
condition is removed.
DESIGN CONSIDERATIONS (CON.)
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the module. An input
capacitance must be placed close to the modules input
pins to filter ripple current and ensure module stability in
the presence of inductive traces that supply the input
voltage to the module.
Safety Considerations
For safety-agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the input
must meet SELV requirements. The power module has
extra-low voltage (ELV) outputs when all inputs are ELV.
The input to these units is to be provided with a maximum
20A of glass type fast-acting fuse in the ungrounded lead.
FEATURES DESCRIPTIONS
Remote On/Off
The DNM/DNL series power modules have an On/Off pin for
remote On/Off operation. Both positive and negative On/Off
logic options are available in the DNM/DNL series power
modules.
For positive logic module, connect an open collector (NPN)
transistor or open drain (N channel) MOSFET between the
On/Off pin and the GND pin (see figure 34). Positive logic
On/Off signal turns the module ON during the logic high and
turns the module OFF during the logic low. When the
positive On/Off function is not used, leave the pin floating or
tie to Vin (module will be On).
For negative logic module, the On/Off pin is pulled high with
an external pull-up resistor (see figure 35). Negative logic
On/Off signal turns the module OFF during logic high and
turns the module ON during logic low. If the negative On/Off
function is not used, leave the pin floating or tie to GND.
