JOEO switching power amplifiers use an intelligent logic control system to ensure optimal performance, safety and reliability. Standard amplifier output ranges from 1 to 480 kVA. Interlocks to prevent vibrator damage or operator injury include: overvoltage, overcurrent, amplifier overheat, vibrator overheat, overrange, phase failures, and power module failures. The amplifier provides drive power for vibrators, excitation coils, blower units, and other auxiliary components.
