High Voltage Power Supplies
Geo-Spark Triple-Charger Pulsed Power Supply
Modular Architecture Pulsed Power Supplies for shallow and oceanic waters.
Description
CUTTING EDGE PULSED POWER TECHNOLOGY
MODULAR ARCHITECTURE
It is possible to combine Geo-Spark Triple-Charger Pulsed Power Supplies to achieve higher energy outputs (the cover image features a common configuration where three Triple-Chargers are combined, achieving maximum 48 kJ energy output).
NEGATIVE ELECTRIC DISCHARGE PULSE
There is no other unit commercially available that allows you to generate a negative High Voltage pulse with such a high dI/dt ratio.
FLEXIBLE ENERGY OUTPUT AND REVOLUTIONARY PULSE SHAPING
The systems has a selectable energy output from 800 J to to 16 kJ per unit, which can be modified by:
selecting the charging voltage from -2000 V to - 4000 V during operation;
changing the total capacitance from 256 to 5120 µF with 256 µF increments.
Since the energy output can be calculated as 2 E = 0.5CV , this creates the option to generate the same energy with different voltage/capacitance combinations. This effectively changes the shape of the pulse, while maintaining the same pulse energy.
The Pulsed Power Supplies are built to last, electronically and mechanically. The housing and frame consist of anodised aluminum and stainless steel 316. Rubber shock absorbers support all the vibration-sensitive components inside the housing.
SAFE AND INTUITIVE OPERATION
All connections, command buttons, switches and status LEDs are front-mounted to ensure direct safe access and intuitive operation.
HIGH QUALITY DRY CAPACITORS
The pulse output has NO electrical oscillations, which affect the acoustic signature. Each capacitor bank contain 2 groups of 256 µF, which can be activated independently. The capacitors are rated for more than 200 million discharges. For example, an one-second discharge rate would give continuous work for six YEARS.
TRIGGERING
Remote triggering of the unit is implemented by a TTL pulse, which is internally converted into a fibre-optic signal to the thyristor trigger device. There is no need for any external opto-isolator on the trigger line. During standby between survey lines, the unit will NOT trip - it will slowly bleed off but will remain ready for the next line
