Altronix EFLOW104NA8D Access Power Controller Features
The eFlow104NA8D distributes and switches power to access control systems and accessories. It converts a 120VAC 60Hz input into eight (8) independently controlled 24VDC PTC protected outputs. These power outputs can be converted to dry form “C” contacts. Outputs are activated by an open collector sink or normally open (NO) dry trigger input from an Access Control System, Card Reader, Keypad, Push Button, PIR, etc. Unit will route power to a variety of access control hardware devices including: Mag Locks, Electric Strikes, Magnetic Door Holders, etc. Outputs will operate in both Fail-Safe and/or Fail-Secure modes. The FACP Interface enables Emergency Egress, Alarm Monitoring, or may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the eight (8) outputs.
Features
- Input: 120VAC 60Hz, 4.5 amp provides reliable power supply for various access control devices.
- Output: 24VDC outputs @ 10 amp supply current ensure optimal performance for connected systems.
- Power-limited outputs: enhance safety by reducing the risk of electrical shock.
- Independently controlled outputs: Eight (8) outputs can be triggered individually, offering flexibility in system configuration.
- Auxiliary power outputs: Eight (8) unswitched filtered aux. power outputs rated @ 2 amp for additional device connectivity.
- Over Voltage protection: protects connected devices from damage due to voltage spikes.
- Short circuit and thermal overload protection: enhances safety and reliability by preventing damage from overload conditions.
- Fire Alarm disconnect: latching or non-latching feature is individually selectable for any or all outputs, ensuring compliance with safety regulations.
- AC fail supervision: includes form “C” contacts to monitor AC power failures.
- Battery supervision: Battery fail & presence supervision with form “C” contacts for enhanced system reliability.
- Low power shutdown: prevents deep battery discharge by shutting down DC outputs when battery voltage is low.
- LED indicators: AC input and DC output LED indicators provide clear visual status of the system.
- Built-in charger: supports sealed lead acid or gel type batteries for convenience and efficiency.
- Maximum charge current: Power Supply Board supports a maximum charge current of 1.54 amp.
- Automatic switch over: instantaneous transfer to stand-by battery power during AC failure ensures uninterrupted operation.
- Zero voltage drop: seamless transition to battery backup without voltage interruption.
