PR580 8-Channel Single-Phase Digital Programmable Power Sequencer
Product Overview
The PR580 is a professional single-phase digital programmable power sequencer designed for audio systems, stage equipment, conference installations, broadcasting facilities and other applications requiring reliable sequential power control.
Powered by a 32-bit ARM processor, the PR580 provides precise and stable timing control for connected equipment. Eight independently controlled sequencing channels help reduce the impact of simultaneous power-on current, allowing amplifiers, processors and other devices to be switched on or off in a controlled sequence.
The unit supports USB, RS-485, RS-232, UDP and optional Wi-Fi control. Its programmable timer, built-in calendar and remote-control capabilities make it suitable for both live-event systems and unattended fixed installations.

Programmable Timing Control
The PR580 allows users to set the sequencing delay according to the requirements of the connected system. Its built-in calendar supports scheduled power-on and power-off operation for periods of up to one year, making it suitable for venues and installations that require automatic daily or periodic equipment control.
Multiple Control Options
The PR580 provides several control and communication methods:
- Front-panel operation
- USB control
- RS-485 communication
- RS-232 communication
- UDP network control
- Optional Wi-Fi control
- Remote internet control
- Multi-unit cascading
Compatible PR580 power sequencers can be connected in a cascade, allowing larger systems to be controlled without purchasing additional central control equipment.
Real-Time Monitoring
Two analog meters display the incoming power voltage and load current in real time. The LCD interface provides clear information about system settings, operating status and control results, helping operators monitor the power system conveniently.
Power Protection and Filtering
The PR580 uses a single-phase 100 A air circuit breaker with current-limiting and short-circuit protection. Each sequencing channel incorporates independent high-performance RFI/EMI power filtering to help provide clean and stable power for connected audio and electronic equipment.
