Power Supply PULSAR HPSDC-12V4X1A — 12V DC, 4A total, four 1A outputs

The PULSAR HPSDC-12V4X1A switched-mode power supply delivers 12V DC with a combined current capacity of 4A, divided into four electrically isolated 1A outputs. Designed for integration into control panels and small enclosures, this compact unit provides regulated DC power for low-voltage security and access control equipment while incorporating short-circuit protection to maintain stable operation.

Advantages

This power supply offers four independently isolated 1A outputs that simplify wiring and fault isolation in multi-device installations. Regulated 12V DC output ensures consistent voltage for cameras, sensors and access modules, reducing the risk of device malfunction due to voltage fluctuations. Built-in short-circuit protection increases system reliability and helps prevent damage to connected equipment. The compact form factor is suitable for mounting inside control panels or enclosures where space is limited.

Suitable for

• Powering CCTV cameras and video modules
• Supplying access control readers and door modules
• Feeding alarm system sensors, detectors and peripherals
• Small installations requiring multiple isolated 12V circuits

Key specifications

• Output voltage: 12 V DC regulated
• Total output current: 4 A (sum of all outputs)
• Number of outputs: 4 isolated outputs, each rated 1 A
• Protection: short-circuit protection on outputs
• Mounting: designed for installation in control panels and small enclosures

How to use

Install the PULSAR HPSDC-12V4X1A inside a suitable control panel or enclosure following local electrical codes. Connect the AC input to the appropriate mains supply using correct wiring and fusing as specified by the installation environment. Route each 12V output to its respective device, keeping polarity correct and using appropriate gauge cabling for 1A loads. Verify output voltage with a multimeter before connecting sensitive equipment and ensure the enclosure provides adequate ventilation and grounding.

Usage recommendations

For reliable operation, group devices by power consumption so no single output exceeds its 1A rating and the combined load stays within 4A. Use short, well-secured wiring runs and proper cable management to minimize voltage drop. Periodically inspect connections and the enclosure for dust or corrosion and confirm that short-circuit protection is functional after maintenance.
