Staircase Timer ZAMEL ASN-01/U 12–240V AC/DC, DIN-mount automatic stair lighting controller

The ZAMEL ASN-01/U 12–240V AC/DC is a DIN-rail mounted staircase timer designed for automatic timed control of stairwell and corridor lighting. Compatible with a wide supply voltage range from 12 to 240V AC or DC, this controller provides reliable switching for temporary lighting needs in residential and small commercial installations. Its compact form factor fits standard DIN mounting rails and integrates into centralized lighting control setups to reduce unnecessary energy consumption while maintaining safety and visibility in common areas.

Advantages

The controller supports a very wide input voltage range, allowing installation in diverse electrical systems without the need for additional power converters. Built for DIN-rail mounting, it saves panel space and simplifies wiring in distribution enclosures. The timer function enables automatic turn-off of lights after a preset interval, reducing energy use and extending lamp life. The device is suitable for both AC and DC supply, offering installation flexibility for different building types and retrofit projects.

Suitable for

• Automatic stairwell and corridor lighting control in apartment buildings
• Temporary lighting in small office buildings and service corridors
• Centralized switching points for common-area safety lighting
• Retrofit projects where wide voltage compatibility is required

Key specifications

• Supply voltage: 12–240V AC/DC
• Mounting: DIN-rail
• Function: timed switching (staircase timer)
• Intended use: control of lighting circuits in stairwells and corridors
• Compatibility: works with AC and DC lighting loads within rated voltage range

How to use

Install the ZAMEL ASN-01/U on a standard DIN-rail inside the electrical distribution cabinet. Connect the supply and load conductors according to the wiring diagram provided by the manufacturer, ensuring correct polarity for DC installations. Configure the timer settings and trigger input as specified in the device manual to set the desired lighting interval. After wiring and configuration, verify operation by initiating a manual trigger and observing automatic shutoff after the selected time period.

Usage recommendations

Use appropriate protective devices and follow local electrical regulations during installation. Verify that connected lamps and loads are within the device's rated voltage and current limits. For installations with mixed AC and DC equipment, confirm correct wiring and polarity. Periodic inspection and testing are recommended to ensure reliable timed switching and safety of the lighting circuit.
