Introducing the New Green Series Linear
Rectifiers from JP Tech
Designed for Reliability
In the 25 years weve been repairing rectifiers, weve learned a lot about what we dont like, so when we designed ours, we left those things out.

• Advanced Design High-Efficiency Transformer: Innovative improvements provide reduced power consumption and extended life.

• Advanced Line Fault Detection: Includes a visual display of over temp faults, line over-current and balance faults, premature shutdown faults and water flow.

• Auto-Phase Rotation Detection: Automatically adjusts to phase sequence with visual line voltage balance displayed by phase.

• Advanced Wiring Design: Single board electronics with reduced circuit complexity provides reliability, fast diagnostics and repair.

• High-Efficiency Aluminum Heat Sinks: Reduced cooling requirements and extended component life.

• Innovative Aluminum Bussing Design: Dramatic reduction in heavy, expensive copper.

• Network Flexibility: Expanded communication flexibility for remote monitoring and control. Analog, serial, and Ethernet connectivity plus six additional common communication protocols make it easy to integrate into an automated line.

• Polymer Panel Design: These attractive panels are Non-corrosive, Non-conductive, and dent resistant

• Advanced Maintainability: Comprehensive fault detection and reporting as well as easy access to all components with removable panels.

Cooling Options:

• Forced Air: Air is forced through the rectifier via high powered fans. This option works well in areas where air quality and turnover is fair to excellent.
• Water: Water or chiller fluids are passed through internal components. This option is very good for challenging locations or poor air quality. Long term maintenance improvement due to lack of exposure to local environment. Water quality must be fair to excellent.
• Internal Closed Loop Water to Water Cooled: Water or chiller fluids pass through an internal water to water heat exchanger. Rectifier coolants are isolated from external coolants. Poor water quality is only exposed to the heat exchanger path.
• Internal Closed Loop Water to Air Cooled: Air is passed through radiator coils to cool rectifier coolants. Rectifier coolants are isolated from external air. This provides sealed rectifier components while still maintaining air cooling standards and benefits. Excellent where air quality varies and water cooling is not an option.

• 460VAC 3-Phase: Standard for all size rectifiers.
• 230VAC 3-Phase: Most sizes up to 10000 Amp can be built for 230VAC lines. Larger sizes available upon request but carry increased design burdens due to extremely large power requirements.
• 120/230VAC 1-Phase: Most small standard rectifiers 250 amps and under will use single phase power.

• Ramp: Voltage or amperage can be ramped from 1 second to 120 minutes. A remote potentiometer provides 1% - 100% ramp time adjustment.
• Digital meters: Increased visibility and measurement accuracy. Offset and span can be calibrated for improved process control.
• Amp Hour Totalizer: Accumulate amp hours for process documentation and chemical adds.
• Amp Hour Controller: Automatically end a cycle at a preset amp hour and/or add chemicals based on amp hours.
• Cycle timer w/alarm: Notify personnel when a cycle ends.
• PLC control: Design a line with automatic controls. Many PLC interfaces available. Standard analog include 4-20mA, 0-5V, 0-10V. Standard digital include RS232, 422, 485, Modbus RTU, Modbus Ethernet, Devicenet slave, Profibus Slave, Directnet. Ethernet: supports TCP/IP, UDP/IP, IPX & Modbus TCP application layer protocol. Other protocols may be available upon request.
• Touchscreen remote/PLC control: Full touchscreen remote with rectifier controlled via embedded PLC. High accuracy and easy to use and install. Multiple recipes with ramp, cycle time, voltage, amperage, amp hour, and digital calibration.

• Ripple chokes: Many ripple based process requirements can be satisfied by reducing ripple using a magnetic inductor (choke) located on the output bus of the rectifier. Standard chokes reduce ripple to 5% (20-100% V/A setpoint).
• Ripple meter: monitor or alarm based on rectifier ripple. Ripple is an early warning of potential plating or rectifier problems.
