The PS71MKII Heavy Duty Power Sequencer is an advanced commercial-grade power management stabilizer engineered to control, regulate, and safely sequence the power distribution to multi-component electronic arrays.
Equipped with high-capacity internal relays supporting a maximum controlled load of 30A, this robust 8-channel rackmount system is designed to prevent massive electrical inrush currents during system startups.
It is meticulously tailored for live concert sound systems, touring DJ setups, commercial broadcasting studios, and theater installations where turning on multiple heavy-drain devices simultaneously could trip main breakers, blow fuses, or generate devastating audio pop spikes through sensitive loudspeakers.
Operating as an intelligent power distribution controller, the unit employs chip-controlled surface-mount technology (SMT) to execute a structured, time-delayed boot sequence across eight universal rear panel sockets.
When activated, it powers components on sequentially from front-end source gear to back-end high-draw power amplifiers, reversing the entire sequence during system shutdown.
Featuring a real-time LCD voltage readout monitor, integrated surge suppression components, and an auxiliary 5V USB charging port on the sleek front panel, it safeguards high-value pro audio and lighting gear while stabilizing overall electrical system uptime.
Features
Intelligent 8-Channel Sequencing Matrix: Automatically triggers the eight rear panel sockets in a chronological sequence with a 1-second delay interval between each channel.
This completely isolates heavy power loads to shield sensitive digital processors and preamps from dangerous startup voltage surges.
Heavy-Duty 30A Maximum Load Capacity: Driven by industrial-grade high-capacity relays engineered to manage high-current distribution safely.
This robust backbone allows the sequencer to effortlessly manage power distribution for multiple high-wattage amplifiers and stage lights.
Integrated Precision Voltage Monitor: Outfitted with an intuitive real-time LCD front panel readout that constantly tracks incoming AC line voltage.
This provides engineering teams with instant visibility into voltage spikes, sags, or electrical instability.
Surface-Mount Technology Core Precision: Built with a highly stable, chip-controlled circuit architecture utilizing precision SMT design.
This layout increases interference immunity, ensures ultra-precise timing intervals, and enhances component longevity.
Universal Multi-Standard Rear Sockets: Features a versatile, multi-format socket configuration across all eight rear outputs.
This universal layout accommodates multiple plug standards seamlessly without the need for fragile external adapters.
Front Panel Auxiliary USB Interface: Includes a built-in 5V USB auxiliary port positioned directly on the front plate.
This provides a clean, regulated low-voltage power supply to run low-power peripheral hardware, rack lights, or mobile diagnostic tools.
