AC Power Requirements
Voltage ratings are quoted elsewhere in this manual.
Typical Currents
At 1500J at 1 pps (AVIP out of circuit); Non PFC charger, the following currents apply:-
Voltage
Peak Current
Average Current
240 VAC 50 Hz
19.5A
7.9A
(At 60 Hz, the peak currents are slightly smaller)
To see clearly the effect of the AVIP board the following measurements are typical:-
240 VAC at 50 Hz supply. 100J at 1 pps output power
Peak Current
Average Current
AVIP IN
2.58A
1.06A
AVIP OUT
9.51A
1.11A
FURTHER REMINDER
If the unit has recently been moved from a cold environment to a warm one, condensation may
have developed, which may cause arcing in high voltage equipment. The operator is advised to
switch the unit on and run the fans for 10-15 minutes before allowing the high voltage to be
switched on. This will allow the unit to warm up to the room temperature, and any condensation
will disperse.
Power Up
When suitably connected to ground, the transducer and AC mains, and the transducer is in the
water, the power can be applied using the ON / OFF switch and circuit breaker. The fans will run,
and the HV OFF / RESET button will illuminate. Select the appropriate power output required and
press the RESET button to reset the internal circuitry. Turn and hold the HV ENABLE KEY &
simultaneously press the HV ON button: there will be a small delay before the HV relays engage,
and then the high voltage will come on as indicated by the illuminated HV ON switch. Any changes
in system parameters (such as power change) will cause the HV to switch OFF, and the unit will
need to be RESET before the HV can be switched on again. If the INTERLOCK indicator
illuminates, check the HV plug / HV junction box.
Trigger Input
Trigger input is by BNC connector. The unit ave trigger (triggers on rising edge) 5 - 20
volts. opto-isolated, or by contact closure, as controlled by the KEY switch. (OUT for +ve key, IN
for contact closure.) The manual key button can be used too and this also shows, by illumination,
when a key pulse has been accepted. (A lockout circuit limits the unit to around 6PPS maximum.)
