- Model VVP-15B - Shore Electrofishers



The Variable Voltage Pulsator Electrofisher Model VVP-15B is a Smith-Root electrofisher that is based on the electrical output waveforms of the Coffelt VVP-15 and MK-22 units. Great care has been taken to improve upon the original designs of the VVP-15 and MK-22. This updated electrofisher provides almost identical control features and metering to allow consistency with previous samplings. Higher efficiency is an added benefit of our generation B, allowing increased samples with less wear and tear on equipment. Input and output connectors remain the same as the original Coffelt design to aid in integration into existing boat and shore systems.

Meters are used to monitor input and output voltage and output current. Crystal controlled time bases are used to insure accuracy of selected output pulse frequencies, duty cycles and the output seconds timer.

Red and green panel lamps show power output status. An automatic electronic circuit breaker will disconnect the output when the unit is overloaded, and automatically reset after a time delay. A toggle switch type circuit breaker provides input protection.

The VVP-15B Electrofisher is powered by a standard 5000W generator. Compatible generators are required to have an unbonded or floating neutral.
