Introducing the New Green
Rectifiers from JP Tech
Designed for Reliability
the 25 years we've been repairing rectifiers, we've learned a lot
about what we dont like. So, when we designed ours, we left those things
High-Efficiency Transformer: Innovative
improvements provide reduced power consumption and extended life.
Line Fault Detection: Includes a visual
display of over temp faults, line over-current and balance faults,
premature shutdown faults and water flow.
Rotation Detection: Automatically adjusts to
phase sequence with visual line voltage balance displayed by phase.
Wiring Design: Single board electronics with
reduced circuit complexity provides reliability, fast diagnostics and
Aluminum Heat Sinks: Reduced cooling
requirements and extended component life.
Aluminum Bussing Design: Dramatic reduction
in heavy, expensive copper.
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.
Panel Design: These attractive panels are
Non-corrosive, Non-conductive, and dent resistant
Maintainability: Comprehensive fault
detection and reporting as well as easy access to all components with
- 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
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
- 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
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.
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
- Ripple meter:
monitor or alarm based on rectifier ripple. Ripple is an early warning
of potential plating or rectifier problems.
