FAQs
How can I reduce or eliminate downtime?
Purchasing and installing a second backup rectifier connected in parallel with the existing rectifier and a DC switch, will virtually eliminate downtime. In this scenario, if a rectifier happens to go down or is being serviced, a backup unit can be brought online within a few minutes. For more information, see our Options document entitled u0022DC Transfer Switchesu0022 for details about DC switch and backup rectifier configurations.
Which is better: air- or water-cooling?
The environment where the rectifier will be placed usually determines the best type of cooling. For harsh, corrosive, or high-temperature environments, water-cooling is best suited.
Do I need a ripple filter?
Ripple is the small AC voltage or current occurring in a DC component as an unavoidable byproduct of rectification. Ripple filtering is a combination of inductance and capacitance used to reduce the level of ripple. Ripple filtering is required on most chrome processes where a decorative or good finish is required. Filtering is also required for loads that are sensitive to AC RMS ripple.
Can I control or monitor the rectifier with my PLC?
Yes. As an option, Controlled Power Company offers single channel computer interface cards for monitoring and/or control of the rectifier. The computer interface card can be configured for 0 to 10 volt, 0 to 5 volt, or 4 to 20 mA signals. Additionally, we offer integrated distributed I/O modules so that communications with the PLC can be performed over Ethernet or serial connections, instead of running analog signals.
Do I need a separate feeder transformer for the rectifier?
The rectifier does not require a separate feeder transformer; however depending on site requirements, one may be necessary. Please discuss this with an electrical contractor or a consultant for further information.
How can I increase my rectifier current output?
A second Series 30 rectifier may be connected in parallel. The parallel control option will allow both units to equally share the load current. Some changes to the existing unit may be required.
What size rectifier do I need?
Rectifier sizing has many variables including part size, anode cell surface area, chemical characteristics, and process time. The chemical or the system supplier usually recommends the rectifier size required for the process.
What is the advantage of a primary SCR, single transformer design?
The low voltage, single transformer design (Series 30) uses primary SCRs for regulation. The SCRs supply AC power to the primary of the transformer. The transformer has a star secondary with a diode connected to each leg for rectification. This design has a low overall component, which makes it very reliable and price competitive.
Which leg of the rectifier is grounded?
The rectifier output is isolated, allowing either leg to be grounded per process requirements.
How can I reduce the floor space needed for rectifiers used in my process?
Controlled Power Company is able to custom-design rectifier cabinets for limited floor space or single-side access. We are also able to provide multiple rectifiers in a single enclosure.
When do I need a DC switch?
A DC switch is used for isolating the output of a rectifier and may be configured for various applications to reduce downtime. When downtime is unacceptable, a DC switch connected to the normal production unit and a standby unit provides a quick means of switching between the two in the event of a failure or for routine maintenance. The DC switch ensures that DC power is not present in the rectifier, so that it can be serviced safely by repair personnel. While the down unit is being serviced, the other unit will operate normally. You will not need to shut down the line when servicing the rectifiers. A DC switch may also be configured to switch one rectifier between multiple tanks.
