Synchronization (Sync)
Yes (see Fig. 7)
Two or more identical units (see Fig. 6). (Use of D. con. terminal 5 will
provide current sharing to within 10% nominal of rated 60°C current.)
Screwdriver adjustment over entire range. Output voltage range is from
18-29.4V. (Multi-turn potentiometer accessible from terminal end of chassis.)
Screwdriver adjustment over entire range. Overvoltage trip range is from
20-34V. Factory setpoint is 31.0V. (Multi-turn potentiometer accessible
from terminal end of chassis.)
Green colored LED illuminates when output is within specified operating range
Red colored LED illuminates if overvoltage, overtemperature, or overcurrent
shutdown occurs. The LED is also illuminated if the output is less than approximately
95% of its adjusted output or if the output is inhibited (stand-by mode).
Provides precise regulation directly at load (see Fig. 3). Maximum total
DC voltage drop between output terminals and load must be limited to
<1.0 V . In addition, the voltage at the output terminals must be limited to
29.4V.
1000 ohms per volt for resistor connected between pins 1 and 2
on TB201 (see Figs. 4 and 5).
Volt per volt for voltage source connected between pins 1 and 2
on TB201 (see Figs. 4 and 5).
Enable/Disable output via TTL compatible signal connected between
pins 6 and 7 of “D” connector (see Fig. 9).
Pins 6 and 7 are fully isolated from all other power supply terminals.
Logic zero (below 0.7 V), short circuit or open circuit disables power
supply output. Logic one (above 2.5 V) enables power supply output.
Current draw from Logic 1 input is less than 4mA.
Output will be within specified limits within 100 ms. of application of
logic “1” signal.
Remote on/off function must be enabled by moving “OUTPUT ENABLE”
switch at terminal end of chassis from “LOCAL” to “REMOTE” position (see Fig. 9).
Conductance signal which indicates adequate input capacitor voltage to
provide 10 ms holdup time when operating -3 model at full output power.
Signal will be asserted when the unit is remotely disabled (AC still present)
or when unit shuts down due to overtemperature (see Fig.10).
Conductance signal which indicates that delivered output voltage, as measured at
the +V and -V terminals, is above its minimum specified value (see Fig. 10).
Conductance signal which indicates that the power supply’s inverter is
functional. At very light loads, this signal may be indeterminate (see Fig. 10).
Input power good, output UV/OV alarms, inverter good and remote on/off
signals are isolated from power supply output and each other for voltages up
to 500 volts, minimum. 3000 VAC isolation from AC input to all auxiliary signals.
Auxiliary signal at approximately 200khz (switching frequency of unit) used for
synchronizing with other equipment.
