PS1-100213-001 SPEC SHEET

The PS1 100213 001 is a specific model number for a power supply unit (PSU) with battery backup manufactured by Millennium Group, Inc. (MGI Access) and sold by suppliers like Synergistics.

This device is a regulated and filtered DC power supply designed to provide 13.8 VDC at 5 Amps. It includes batteries, an enclosure with key lock, fuse protection, monitoring outputs, and an LCD indicator for power status and current consumption.

What is it used for?

The PS1 is used to power Millennium controller boards and associated access devices. It can supply power to up to 15 E-series single-door controllers or 8 two-door controllers. While also conditioning the RS-485 data line to maintain reliable communication over long distances (up to 4,000 feet).

The PS1 is a professional-grade, regulated DC power supply. Specifically to support Millennium systems. It is designed not only to deliver power, but also to protect, monitor, and stabilize both power and communication lines in multi-controller installations.

PS1 100213 001

According to the Millennium Manuals, the PS1 is a centralized power. that system is a backup, protection, monitoring, and RS-485 conditioning solution. It is designed for mission-critical access device environments where uptime, communication integrity, and equipment protection are essential. It goes beyond basic power delivery to actively enhance system stability, security, and scalability.

The PS1-100213-001 delivers regulated, protected, and battery-backed DC power to access systems and ensures stable, continuous operation even during AC power failures.

The PS1 powers Millennium controllers and related access devices, including readers and communication modules. It is ideal for both single-door and multi-door installations. Each unit capable of supporting multiple controllers. Additionally, the PS1 conditions the RS-485 communication line, enabling reliable long-distance data transmission in commercial, industrial, and corporate security environments, where system uptime and supervision are essential.

Electrical Design & Power Quality

  • Provides a stable 13.8 VDC at 5 Amps, ideal for access controllers, readers, and related peripherals.

  • Filtered DC output reduces electrical noise, protecting sensitive electronics and improving long-term reliability.

  • Current-limited output automatically protects the system during short circuits or overload conditions, preventing damage to connected devices.

Electrical Design & Power Quality

His advanced filtering reduces electrical noise and voltage fluctuations, protecting sensitive electronics and ensuring reliable controller performance. The current-limited DC output automatically safeguards connected devices against short circuits and overloads. These features enhance system reliability, minimize the risk of equipment damage, and promote long-term, uninterrupted operation in professional security installations.

Monitoring, Supervision, and Security

  • AC failure monitoring, featuring a Form A relay output, enables real-time reporting of power loss to the  Millennium access control for alarm panel.
  • A cover tamper switch with a Form A output monitors the enclosure door status, offering an added layer of physical security.
  • A front-mounted LCD display allows quick verification of voltage output and current draw without opening the cabinet.

Communication Line Conditioning

The PS1 power supply features integrated communication line conditioning to ensure reliable RS-485 data transmission in access systems devices. A dedicated secondary board supplies the necessary biasing voltages for the RS-485 network, maintaining stable and clean signal levels. This design minimizes noise, signal degradation, and communication errors, enabling controller boards to communicate effectively with the Site Control Unit over distances up to 4,000 feet. As a result, the PS1 enhances data integrity and delivers consistent system performance, even in large or electrically noisy environments.

Physical Construction & Installation

The PS1 100213 001 features a heavy-duty metal enclosure engineered for secure and reliable indoor installation. An MGI key lock provides controlled access, safeguarding internal components against tampering. A cover tamper switch continuously monitors the enclosure door and reports unauthorized access to the system.
For simplified installation and maintenance, the PS1 ships fully assembled with batteries, enclosure, and monitoring components. The front-mounted LCD display enables installers and technicians to quickly verify output voltage and current consumption without opening the cabinet. Designed for controlled environments, the unit operates in temperatures from -10°C to 40°C (14°F to 104°F) and humidity below 90% non-condensing, making it ideal for electrical rooms, control panels, and security closets in professional access control installations.

Features

For system supervision, the PS1 includes AC failure monitoring via a Form A relay output and a cover tamper switch for enhanced security. It features AC and battery fuse protection to safeguard both power input and backup systems. The PS1 also conditions the RS-485 communication line, maintaining clean and stable data transmission over distances up to 4,000 feet. A front-mounted LCD display provides quick verification of output voltage and current consumption. UL 294 and CA 1950 listings ensure suitability for professional access control installations.
