The Command Access Technologies PS210 Linear Power Supply is a regulated 24VDC access-control power supply for compatible electrified commercial door hardware. Designed for applications such as electric latch-retraction exit devices, electrified locksets, electric strikes, and magnetic locks, it delivers 1.5 amps continuous at 24VDC with a 2.5-amp boost capability for short-duration inrush requirements. The PS210 uses a single solid-state input/output channel and is housed in a compact metal enclosure for professional low-voltage security installations.

Power Supply Sizing for Commercial Door Hardware

The PS210 provides a 24VDC regulated source rated for 1.5A continuous operation, with a separate 2.5A short-duration boost capability. The boost rating is not the maximum continuous load rating. Match the connected latch-retraction solenoid, electrified lock, strike or control equipment to the manufacturer’s requirements before selecting this model.

Installation Checklist

• Load calculation: Confirm total steady-state current and simultaneous energization, including inrush demands, wire-run voltage drop and the rating of any external relay or controller.
• Control interfaces: Use the manufacturer’s current wiring diagram for solid-state input/output connections and any specified alarm or release interface.
• Physical mounting: Confirm enclosure mounting, AC feed, field wiring separation, environmental requirements, service clearance and required branch protection.
• Final test: Verify regulated 24VDC under load and check that each connected device actuates and returns to its safe specified state.

Supplied scope: PS210 power supply assembly; access controller, locking hardware, field wiring, door-to-frame transfer and optional backup equipment are separate unless expressly included.

Important compatibility note: The manufacturer describes the PS210 as supporting up to two suitable electric latch-pullback or lock devices through one output, provided that simultaneous startup current, holding load, conductor size, wiring distance, and duty cycle remain within its published capacity. One input/output does not mean two independently controlled outputs. Verify the exact connected hardware's requirements and Command Access power-supply compatibility matrix before specifying a system.

Key Features and Benefits

• Regulated 24VDC power: Supplies 24 volts DC for properly rated low-voltage electrified locking components, subject to factory tolerance and circuit loading.
• 1.5A continuous output: Designed for continuous operation within its rated 1.5-amp output capacity.
• 2.5A short-duration boost: Provides temporary inrush support for select motorized or solenoid-driven exit devices when operated within manufacturer duty-cycle limits.
• Single solid-state input/output: One independently triggered control channel with a corresponding regulated and protected 24VDC output.
• Resettable output protection: One 1.5A auto-resetting, PTC-protected output helps limit damage caused by shorts and overload conditions.
• Regulated linear design: Designed to deliver stable low-voltage DC and accommodate the high inrush/hold characteristics of compatible electrical latch-retraction equipment.
• 120VAC input: Designed for 110-120VAC mains power, 60Hz, with a manufacturer-specified 2A input fuse rated at 250VAC.
• Diagnostic status indicators: Red AC-power LED and green DC-output/channel LED assist installers and service technicians.
• Removable wiring connectors: Euro-style terminal connectors simplify service and electrical terminations.
• Overvoltage and output protection: Includes circuit protection and an adjustable output-voltage trim control, per factory instructions.
• Fire-alarm integration: Manufacturer wiring instructions describe a fire-alarm link/tie-in using the unit's input. Plan and test disconnect behavior according to the local code and the current installation guide.
• Commercial metal enclosure: Metal housing measures 11 inches wide x 11 inches high x 4 inches deep with 1/2-inch and 3/4-inch knockouts.
• Removable cover: Hingeless, removable enclosure cover. Cam lock not included; confirm any security-locking hardware needed for the installation.
• UL 294 6th Edition: Manufacturer documentation identifies the PS210 as UL 294 Sixth Edition listed; verify any project-specific CSA and other requirements against current certificates.
• Made in USA: Manufacturer product literature identifies the PS210 power supply as built in the United States; confirm origin if a project requires formal domestic-origin documentation.

Product Specifications

Typical Commercial Applications

• Electrified access-control mortise and cylindrical locks requiring a regulated 24VDC supply
• Compatible motor-driven latch-retraction exit devices and electric exit trim
• Compatible solenoid-driven commercial panic-device electrification hardware
• Electric strikes and magnetic locking devices within approved 24VDC current requirements
• Commercial office, institutional, healthcare, education and facility-access installations
• Replacement of a Command Access PS210 or professionally specified equivalent having one input/output and suitable electrical output ratings

PS210 versus Other Command Access Power Supplies

The PS210 has one solid-state input and one protected output for 1.5A continuous 24VDC operation and a brief boost capacity. Other Command Access models such as PS220/PS220B and PS440B offer different output counts, total amperage, and battery-backup options. Select the power supply according to the number of independently controlled doors, device inrush/hold current, expected simultaneous activity, battery-backup needs, and fire-alarm-interface design.

Installation and Ordering Checklist

1. Confirm the exact model: Order PS210, not a board-only replacement or a different Command Access power supply.
2. Review line power: Have qualified personnel provide the specified 110-120VAC, 60Hz branch-circuit power and observe electrical-safety procedures.
3. Calculate connected hardware current: Verify the cumulative continuous, boost and simultaneous inrush loads for all connected hardware; ensure the protected output is not overloaded.
4. Match control requirements: The PS210 has one solid-state input/output channel. Two devices may share a compatible output only when manufacturer conditions and the total load allow it; separate control requires another design.
5. Confirm dry-contact trigger wiring: Follow the current factory installation diagram; do not apply voltage to an input intended for a dry contact.
6. Check fire-alarm tie-in and egress: Coordinate any fire-alarm control, locking logic, life-safety requirements and egress code compliance with the applicable professionals.
7. Protect field wiring and mount securely: Use the correct conduit knockouts, electrical grounding, wire gauges, separation and enclosure installation according to the manufacturer's instructions.
8. Test the completed system: Verify red and green status LEDs, output voltage, lock or latch-retraction function, fire-alarm behavior when specified, and electrical performance during startup.
