Power Supply ORNO open-frame 12V DC 500W OR-ZL-1640

The ORNO open-frame power supply OR-ZL-1640 provides a regulated 12 V DC output with up to 500 W maximum power in a compact open-frame design. Intended for integration into server racks, industrial equipment and custom electronics projects, this unit offers stable 12 V power for computing, control systems and peripheral devices. Its exposed-frame construction supports efficient heat dissipation and flexible mounting inside cabinets or enclosures where airflow and access for wiring are available.

Advantages

The open-frame construction reduces enclosure size and improves cooling by allowing unrestricted airflow around components. The supply delivers a continuous 12 V output with sufficient headroom to support multiple peripherals and control circuits typical for rack-mounted and industrial applications. The compact footprint and standard mounting points facilitate installation in custom systems, while the design emphasizes straightforward integration with existing server or control hardware.

Suitable for

• Server racks and network equipment requiring 12 V DC power
• Industrial control cabinets and automation panels
• Custom electronics and prototyping projects
• Peripheral devices, sensors and low-voltage actuators

Key specifications

• Output voltage: 12 V DC (regulated)
• Maximum output power: 500 W
• Form factor: open-frame (exposed PCB and components)
• Cooling: convection and chassis airflow dependent (open design)
• Mounting: chassis or rack integration with standard fixing points
• Typical applications: servers, industrial equipment, electronics assemblies

How to use

Mount the unit securely inside a cabinet or rack with adequate airflow and access for input and output cabling. Connect the AC input according to applicable electrical codes and ensure protective earth is connected where required. Route and secure the 12 V DC output wiring to the load, observing correct polarity and using appropriately rated wire and connectors for the expected current. Verify output voltage with a multimeter before connecting sensitive equipment and add fusing or overcurrent protection on the DC output as needed for the installation.

Usage recommendations

Install the open-frame supply where ventilation is unobstructed and temperatures remain within the device’s operating range. Provide dust protection if used in dusty environments and include external filters or fans if higher airflow or cooling is required. Use appropriate overcurrent protection on both AC and DC sides and follow local wiring regulations during installation.
