DESIGN & FEATURE CONSIDERATONS

Remote On/Off

Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and

off during a logic low. To turn the power module on and off, the user must supply a switch to control the

voltage between the on/off terminal and the -Vin terminal. The switch can be an open collector or

equivalent.

A logic low is -0.7V to 0.8V.

A logic high is 2.5V to 5.5V.

The maximum sink current at on/off terminal during a logic low is -1mA. The maximum allowable

leakage current of the switch at on/off terminal (2.5 to 5.5V) is 50uA.

Over Current Protection

To provide protection in a fault (output overload) condition, the unit is equipped with internal current

limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit

inception, the unit shifts from voltage control to current control. The unit operates normally once the

output current is brought back into its specified range.

Input Source Impedance

The power module should be connected to a low ac-impedance input source. Highly inductive source

impedances can affect the stability of the power module. In applications where power is supplied over

long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure

startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is

recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz)

capacitor of a 10uF for the 24V and 48V input devices.

Maximum Capacitive Load

The DMW Series has a limitation of maximum connected capacitance at the output. The power module

may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time.

For optimum performance we recommend 220uF maximum capacitive load for dual outputs and 470uF

capacitive load for single outputs. The maximum capacitance can be found in the Output Voltage /

Current Rating Chart.
