Product Description

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.

High conversion efficiency > 91 percent
Emergency stop (E-stop) on front panel
Optional remote control panel (RCP) that duplicates functionality of amplifier front panel
Space saving low-profile cabinet for amplifiers with outputs from 1 to 6 kVA
LCD display for status and diagnostic messages
Meets or exceeds international requirements for safety and EMC
Selectable BNC connection on front panel and rear cabinet for drive input
Low harmonic distortion < 0.5% at typical testing frequencies
Designed for continuous use over extended periods of operation
