Series 70 AutoCoat MAC Rectifier (100 V - 450 VDC, 200 A - 400 A)
The Series 70 Auto Coat Rectifier is a compact, front-access DC power supply designed for modern e-coat applications, including both standalone use and Modular Anode Control (MAC) systems. Available in 6-pulse (Model 706) and 12-pulse (Model 7012) configurations, it delivers 400V–450V and 200A–400A output ratings with precision regulation. Built for demanding automotive and industrial environments, it offers advanced anode monitoring, dedicated outputs, and extensive control options. With high efficiency, low ripple performance, and flexible PLC integration, the Series 70 ensures reliable, consistent power for optimized coating processes.
Features
- Compact, Space-Saving Design – Small footprint with full front access eliminates the need for side or rear clearance, easing installation in tight spaces.
- Flexible Configurations – Offered in both 6-pulse and 12-pulse SCR models, providing options for ripple control and efficiency to match application needs.
- Enhanced Anode Monitoring – Integrated anode monitoring improves process quality and enables tighter control of e-coat performance.
- Multiple Output Capability – Provides up to two dedicated outputs at 200A and up to four at 400A, supporting complex systems with multiple anodes.
- Advanced Controls & Safety – Features include voltage/current meters, ramping controls, emergency shutoff, and automatic overload shutoff for reliable operation.
- High Efficiency & Stability – Operates at 95% typical efficiency with precise ±0.5% voltage and current regulation, reducing energy waste while ensuring consistent output.
- Flexible PLC Integration – Compatible with various PLC manufacturers and distributed I/O configurations, allowing seamless system integration.
- Built for Harsh Environments – Designed to withstand industrial conditions with protective door interlocks, high humidity tolerance, and robust enclosure options.

FAQs
Can the Series 70 AutoCoat be used in a 1- or 2-zone standard e-coat system configuration?
Yes! The Series 70 AutoCoat is available in a standard model, which has controls for a conventional monorail or batch type e-coat configuration, plus a single-output bus for connection to multiple anodes.
Do I need a separate anode monitoring system in an MAC system with the Series 70 AutoCoat?
No. The Series 70 AutoCoat has built-in current sensing for each output that is connected to the tank. The current values can be sent either over Ethernet / Serial connections with distributed I/O or analog 4-20mA signals.
How can I reduce the floor space needed for rectifiers used in my process?
Trystar 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.
Does the Series 70 AutoCoat offer PLC control and monitoring?
Yes! The Series 70 AutoCoat may be provided with internal distributed I/O modules, which allow communication with a PLC that digitally controls and monitors multiple rectifiers at one time (e.g., in an MAC system). Whether provided by Trystar or another manufacturer, this PLC can also communicate with a manufacturing plant’s PLC or centralized monitoring system for expanded monitoring and control.
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 “DC Transfer Switches” for details about DC switch and backup rectifier configurations.
