Unit Voltage Specs & Checks
Sultan Acoustic Wave Series
45
Sultan 234
Specified ranges (supply dependent): 90-260VAC,
12-30VDC, 36-60VDC). For suspected power issues
ensure user supply is appropriate & consistent.
If using AC power you can check the power supply
for faults by reading the DC +/- terminals with a
multimeter set to DC. This terminal will produce 15-
16VDC stable. If this value is lower or inconsistent
you may a problem with the internal power supply.
Unit performance will be affected if the unit detects
voltage below 9VDC. If ‘V in chk’ is on the unit will
trigger its failsafe routine. If V in chk is off the unit will
display V fail on the LCD.
Sultan 2
Specified ranges: 12-30VDC.
Unit performance will be affected if power drops
below 7VDC. If ‘V in chk’ is on the unit will trigger its
failsafe routine. If V in chk is off the unit will display V
fail on the LCD.
Transducers
The Transducer power (red wire) should draw
8-10VDC. If this figure is too high or too low check
Sultan power & supplied power as above.
Check Resistances between transducer wires
(approximate values):
Black - Blue = 15.6Kohms
Black - White = 15.6Kohms
Resistances between transducer terminals
(approximate values):
Black - Blue = 16.2Kohms
Black - White = 16.2Kohms
