OUXIPER PDP-25A 25A Dual DC Power Supply Auto Transfer Switch CB

OUXIPER PDP-25A Dual DC Power Supply Automatic Transfer Switch – CB Type

The OUXIPER PDP-25A is a heavy-duty CB-type dual DC power supply automatic transfer switch engineered for industrial, commercial, and critical infrastructure applications. With seamless switching between two independent DC power sources, this 25A / 5.5KW unit ensures uninterrupted power delivery to your equipment — zero downtime, zero interruptions.

Made in Beijing, China.

Key Features

• Redundant Dual DC Input: Accepts two separate DC power sources (12V–220V DC each); automatically switches to the backup when the primary source fails — seamlessly and instantaneously.
• Overcurrent Protection: Both input channels and all 6 output channels are protected by built-in DC air circuit breakers with 110% overcurrent capacity.
• High Output Efficiency: Delivers ≥98% output efficiency with a rated output of 5.5KW at 25A.
• 6-Channel Output: Output branching into 6 independent channels (customizable to meet specific project requirements).
• Isolation Between Sources: Meets strict isolation requirements between dual power supplies, preventing mutual interference during DC system grounding faults.
• Low Noise Operation: Operates at ≤40dB for quiet, reliable performance even in sensitive environments.
• Rack-Mount Design: 2U standard 19-inch rack-mount enclosure for easy integration into existing infrastructure.
• Wall Terminal Wiring: Secure through-wall terminal wiring for both input and output connections.
• Imported Brand Components: All major electrical components sourced from trusted international brands for reliability and longevity.
• Wide Operating Range: Functions across 0–60°C ambient temperature and 0–90% humidity.

Technical Specifications

Applications

The PDP-25A is designed for environments where uninterrupted DC power is mission-critical, including:

• Data centers & server rooms
• Telecommunications & mobile infrastructure
• Banks & financial institutions
• Airports & high-speed rail systems
• Industrial automation & chemical plants
• Hospitals & sports facilities
• Household backup power systems

How It Works

The PDP-25A accepts two independent DC inputs with different voltage levels. The unit automatically prioritizes the higher-voltage input as the primary source. If the primary supply fails, it instantly switches to the secondary source — achieving truly seamless, no-interruption transfer. This eliminates the vulnerability of a single-source power setup for critical DC equipment.

Frequently Asked Questions

Q: What is the OUXIPER PDP-25A dual power supply automatic transfer switch used for?

A: The OUXIPER PDP-25A is a CB-type automatic transfer switch designed to manage two independent DC power sources (12V–220V DC). It automatically switches to a backup DC supply when the primary source becomes unavailable, ensuring continuous power to connected equipment. It is ideal for data centers, telecom infrastructure, hospitals, banks, industrial automation, and other settings that require uninterrupted DC power.

Q: Does the PDP-25A support different input voltages on the two DC channels?

A: Yes. The PDP-25A is designed to accept two DC inputs with different voltage levels simultaneously. The system automatically prioritizes the higher-voltage input as the primary source and seamlessly switches to the secondary input if the primary fails — with no interruption to downstream equipment.

Q: How many output channels does the PDP-25A provide, and can they be customized?

A: The standard PDP-25A provides 6 independent output channels, each protected by overcurrent circuit breakers. The number of output channels can be customized to meet specific project requirements — contact the vendor for custom configurations.

Q: What type of enclosure does the PDP-25A use and how is it installed?

A: The PDP-25A uses a 2U standard 19-inch rack-mount enclosure, making it fully compatible with standard server/equipment racks. Wiring is handled through wall terminals on both input and output sides for a secure, professional installation.

Q: What overcurrent protection does the PDP-25A offer?

A: The PDP-25A includes built-in DC air circuit breakers on both input channels and all output channels. The unit supports 110% overcurrent output capacity, protecting connected equipment from current surges while maintaining stable operation.
