1. DIP switch group S5, switch numbers 1 - 3 are for changing the
Back-Up Timer Interval
(See Table 2). This adjustment
sets the amount of time the MDP’s internal back-up battery remains connected to the output/load when a low voltage
event is detected.
2. DIP switch group S5, switch numbers 4 - 6 are for changing the
Back-Up Trigger Voltage Threshold
(See Table 3). This
adjustment sets the voltage at where the internal battery is applied to the output/load and the input source (vehicle
battery) is disconnected.
3. DIP switch group S4, switch numbers 4 - 6 are for changing the
Back-Up Hysteresis
(See Table 4). Hysteresis sets a
voltage level above the back-up trigger level for the reconnection of input source and disconnection of internal battery
(see table 4). Hysteresis should be set after determined the amount of voltage drop from the DC source (vehicle battery)
to input terminals of the MDP, when the intended output load current is at its maximum level.
Note: Remember to take
into account at least 2 amps for internal charger. The internal charger can draw approximately 2 amps from the input source to
charge the internal back-up battery if it is deeply discharged.
4. DIP switch group S4, switch numbers 1- 3 are for changing the
Charger Re-start Interval
(See Table 5). The charging
time of the internal battery is not settable; it is dictated by the battery state of charge, battery condition and temperature.
In order to reduce the current drain on the vehicle battery the internal battery charger turns OFF once it completes a
charging cycle. However the time at which the charger will turn back on to refresh the charge on the internal battery is
adjustable.
