CSP-CSPD-8000/2- Section 1 Page 10 of 30
INTRODUCTION
This manual covers the following CSP-D models available from AAE:
1) CSP-D 1200. Based on the highly proven CSP1500, the CSP-D 1200 has a high
voltage charger rated at 1500 joules per second, and can supply up to 1200 joules of
energy per shot into boomer and sparker loads. The CSP-D allows the user to select
HI and LO power levels this can effectively tune the source to a lower frequency
response. The CSP-D 1200 can be supplied with just 700J of energy storage
capacitors which allows for future upgrading.
2) CSP-D 2400. A higher capacity version of the CSP-D 1200, the CSP-D 2400 can
operate with low energies for boomer operations or large energies which are tailored
for use with the Squid 2000 sparker.
3) CSP-D 700. This is a lower capacity version of the above units and can be upgraded
to the full 1200 or 2400 joule specification at the factory.
The CSP-D’s incorporate many common parts and apart from the differing amounts of
energy storage, can be considered essentially as the same. All units feature a switchable
soft start ‘power save’ circuit; AVIP (Automatic Variable Input Power) which allows the
units to be operated from reduced generator sizes when operating at low output powers:-
Traditional high voltage power supplies (bang boxes) will charge the energy storage
capacitors at a fixed high rate for example at 1500J per second even when the average
energy drawn from the capacitors is less; a typical example may be 100 J at 3 pps
(300J). This results in a rapid capacitor charge rate for 67 mS followed by nothing, until
the next discharge / charge cycle. This charge / no charge operation can often result in
generator hunting as the load changes, and may mean that a larger generator is needed
than would be the case if the power requirement was averaged over time. By reducing
the peak charge rate, the generator hunting is all but eliminated, and a smaller capacity
generator is required. The AVIP circuitry will automatically adjust charge rate from 20%
to 100% of specification, thus lowering the peak charge rate to just 300 J / second
compared to bursts of 1500J/second. The circuitry also features a soft start function,
which may take around 20 seconds before the charge rate is ramped up to the correct
amount for the task in hand.
The CSP-D’s allow the user to effectively ‘tune’ the sound source to operate at a lower
frequency by lowering the operating voltage and increasing the capacitance to supply the
correct energy to the sound source. This maybe effective in certain instances where
more penetration is required.
The CSP-Ds monitor the output of the system for open circuit fault conditions and over
current fault conditions, limited to approx 5000A.
