Detex 90-800 Series 800 Power Supply — 24VDC, 1 Amp Continuous
The Detex 90-800 is a complete, enclosed 24VDC filtered and regulated power supply designed for compatible commercial electrified exit devices, electric dogging, delayed egress and electromagnetic locking systems. It accepts standard 120VAC input and supplies 24VDC at 1.0 amp continuous to approved electric locking and access-control components. A built-in fire-alarm interface supports the release of appropriately wired fail-safe locks when required by the installation.
Additional Product Specifications and Ordering Guidance
Power-Supply Sizing and System Compatibility
Detex electrical power accessories must be sized for the selected exit-device or alarm controller rather than chosen solely by their nominal voltage. The power supply's regulated current, connected loads and emergency-release requirements affect reliable door operation.
Factory item on this listing: DTX-90-800.
Product Selection and Installation Checklist
- Match the original power or battery-eliminator model and approved Detex host application before substituting a different version.
- Calculate combined continuous and starting currents, cabling voltage drop and the required input power source.
- Review any alarm supervision, power-loss indication, battery/standby requirements and control-panel interfaces for the selected assembly.
- Confirm enclosure, mounting ventilation, protective wiring, fuse ratings and field installation requirements.
Acceptance and Service Verification
Test output under normal operating load, startup/inrush behavior where applicable, and the host exit/alarm system's expected power-failure response.
Factory Package and Related Components
The specified Detex power or battery-eliminator assembly only; additional controllers, batteries, housing and wiring depend on the selected model. Consult the original model specifications below when matching the factory SKU to an existing opening.
Model selection is important: The 90-800 provides fixed 24VDC output and does not include a battery-charging circuit or battery backup. Unlike the separate Detex 80-800, it is not field-selectable for 12VDC/24VDC and does not offer the 80-800's integrated battery charger. The listed 90-800 is the standard 120VAC-input configuration, not the optional 90-800IN input-voltage version or 90-800LT less-transformer version.
Key Features
- Genuine Detex Series 800 power supply: Model 90-800, a complete assembled power supply in a commercial-duty metal enclosure—not just a circuit board or transformer.
- Filtered, regulated 24VDC output: Stable DC power for compatible electronic door-locking hardware and access-control components.
- 1.0 amp continuous output rating: The total system load must remain within Detex's rated output and applicable circuit specifications. Do not assume two terminal connections permit 2A total output.
- Standard 120VAC input: Detex installation literature specifies 120VAC, 60Hz, 0.65A maximum for this model. Use suitable branch circuit, wiring and disconnect procedures.
- Two 24VDC output terminal sets: Detex's 90-800 wiring diagram shows separately accessible positive/negative output terminal blocks, with the supply rated 1 amp continuous.
- Fire-alarm loop input: Supports fail-safe lock release where the unit is correctly integrated with the building's fire alarm and approved locking system. Configure wiring for fail-safe response according to the Detex instructions and local codes.
- LED system-status indication: Visual indication assists installation checks and system troubleshooting.
- Auto-resetting circuit protection: Built-in protection supports reliable operation and service after an electrical fault has been corrected.
- Service on/off switch: Main power control supports inspection and service by qualified personnel.
- Heavy-duty 18-gauge enclosure: Protective indoor housing for electrical power-supply components.
- Class 2 rated output: Designed for compatible commercial access-control and electrified door-hardware installations.
- No integral battery charging: The 90-800 does not include the battery-charger, low-battery-disconnect or standby backup features of the 80-800.

Shipping Information
The Shopify shipping weight is set to 10 lb as a provisional estimate. Detex-packed shipment weight and outside carton dimensions for this exact 90-800 model could not be verified. Confirm actual packaged weight and carton dimensions before rating freight or UPS shipments and update the shipping profile if the distributor's shipment differs.
Ordering and Electrical-Safety Notes
Specify Detex 90-800 for 120VAC-input to 24VDC / 1.0A continuous power. Confirm the total connected load, voltage, wiring length, fail-safe fire-alarm interface, emergency egress requirements, and compatibility with the exact electric locking product. Do not substitute this model for the 80-800 where battery-backed operation or field-selectable 12V output is required. The 90-800 is intended for indoor use only. All high-voltage wiring and fire-alarm interconnection must be performed by qualified personnel with power disconnected, following the current Detex 103158 instructions, applicable electrical and life-safety codes, and the authority having jurisdiction.
