Q300 modular rectifiers
Air-cooled modular DC power
The Quasar Q300 brings modular three-phase DC power to electroplating and anodizing. Its air-cooled platform uses stacked power modules to match the process output and installation.
Up to 30 kW
Maximum output power
Up to 1,800 A
Maximum DC output current
5–450 VDC
Available output voltage ratings
Output ratings depend on the selected configuration. Maximum voltage, current and power are separate limits, not a simultaneous operating point.
Modular capacity. Practical process control.
The Q300 is an air-cooled switch-mode rectifier with two or three stacked modules. Current or voltage control, manual or automatic operation, amp-hour counting and programmable ramps support production requirements. Reversing and pulse waveforms are optional.
Air cooling
An air-cooled platform with IP21 enclosure protection. Provide the specified ventilation and service access.
Modular output
Select module and output configurations to meet the load. The published maximum power, current and voltage are separate limits.
Plant integration
Configure industrial communications, analog PLC control and coordinated operation of compatible units for the application.
Stack the capacity around your process.
The Q300 platform is air cooled. Two- and three-module configurations have different overall heights and output ratings. Specify the complete stack and control arrangement with ACRS.
Q300 modular air-cooled stack
Choose a two- or three-module air-cooled stack. Final output and installation dimensions depend on the selected configuration.

Depth
Overall stack height must be confirmed for the selected module configuration. Original dimensional artwork uses millimeters; the verified width and depth above are converted to inches.
Options & accessories
Configure the Q300 around your process, controls and installation. Options are specified separately; availability depends on the selected output and system configuration.
Options
- Reversing output. Switch between forward and reverse output polarity.
- Pulse output. A 1 ms option is available for resistive loads; recipe, software and component selection determine performance.
- Lower ripple. Ripple below 1% is available on request.
- Industrial communications. Profibus-DP, DeviceNet, EtherNet/IP, PROFINET and Modbus TCP.
- Plant integration. Analog PLC interface, IOS terminal block and a communications-output enclosure.
- Multi-tower operation. Interconnect compatible units for greater output under coordinated control.
- UL-compliance configuration. Ask ACRS to confirm the required component and certification scope for the specific configuration.
- Emergency stop. Specify the required external safety interface and control arrangement.
Accessories
- REM8E remote control. 24 VDC / 24 VAC supply.
- REM8 remote control. 85–264 VAC supply.
- REMMT1. Rectifier test equipment.
- RSM09A / PSM08A. CPU090 / CPU080 simulators, respectively.
- Q800 Cabinet. Cabinet platform for compatible tabletop rectifiers; configuration and power distribution are specified separately.
