D1: Output Voltage Monitor
D1 is intended for monitoring the bus voltage of a battery-
buffered system. It indicates that the system is powered from
the battery and can for instance be used as warning signal or
to switch off a part of the load. If the output voltage drops below
Vo low D1, the D1 signal (open-collector) goes to high
impedance. I D max <50 mA. The D1 output is protected by a
Zener diode against transients up to 75 V (for models with
Vo max >50 V up to 90 V). In double-output models D1 monitors
only output 2.
In applications without battery-buffering the D1 signal may not
be suitable, since smaller dynamic load changes may cause
D1 to trigger. For such applications D5 with a trigger level of
approx. 85% Vo nom should be chosen (e.g., for bus voltage
24.7 V, trigger level at 21 V).
D5: System Voltage Monitor (Battery Deep)
D5 monitors the output voltage Vo (Vo2 in double-output
models) or the lowest admissible voltage of a connected
battery (battery deep discharge). The definition of D5 is similar
to D1, but the trigger level is lower. When Vo drops below the
value specified in the table below, the D5 signal (open-
collector) goes to high impedance. I D max < 50 mA. The D5
output is protected by a Zener diode against transients up to 75
V (for models with Vo max >50 V up to 90 V).
In systems without battery support, D5 signals that Vo (or Vo2 )
is going to drop below a safe value.
In battery-buffered systems, D5 indicates that the battery has
reached its deepest discharge level prior to getting damaged.
The D5 signal can be used for instance to disable loads, save
data, or to start a controlled switch-off of running processes.
Adjustment of Threshold Levels (D1/D5)
Pin 7 of the D-SUB connector allows for adjustment of the
threshold levels of D1 and D5. Both levels are influenced by
the voltage divider Rx / Ry. Resistor Rx to pin 3 (VCC) lowers
the levels, whereas Ry to pin 1 (GND1) increases them (see
fig. 22).

Option S: Shutdown
Reduces the output power to approx.1 W, i.e., the converter is
not fully disabled. In a no-load condition Vo drops below 6.2 V;
see fig. 23. In double-output models, only output 2 is
influenced.

Sys-OK: Status
This function allows for checking in a battery charger
application, whether the output follows the external control
signal at the R-input (coming for instance from the temperature
sensor). Refer to table 19.
The open-collector output Sys-OK is protected by a Zener
diode against transients up to 75 V (for models with Vo max >50
V up to 90 V). Current <50 mA.
