Shopcorp AHC15A Weekly Programmable Timer
The Shopcorp AHC15A is a digital weekly programmable timer designed to automatically switch compatible electrical loads according to scheduled ON and OFF times.
Operating from a 110VAC, 50/60Hz supply, the timer provides up to 16 ON and 16 OFF programmed events and supports recurring 24-hour / 7-day scheduling.
Its DIN rail format makes it suitable for installation in control panels, distribution enclosures, lighting systems, and equipment automation applications where scheduled switching is required.
16 ON / 16 OFF Weekly Programming
Users can configure up to 16 separate ON events and 16 separate OFF events.
This allows scheduled equipment operation throughout the week without requiring manual switching each time.
Possible applications include:
- Lighting control
- Signage
- Electrical equipment scheduling
- Control panels
- Pumps and compatible equipment
- Ventilation systems
- Commercial lighting
- Building automation
- Recurring equipment operation
- Other properly rated electrical loads
24-Hour / 7-Day Scheduling
The timer supports programming across a full weekly cycle.
Schedules can be configured according to the required operating periods, making the timer useful for applications that run at specific times on selected days.
LCD Display and Programming Interface
The front LCD display allows programmed times and operating information to be viewed directly from the timer.
Front-facing controls provide access to the scheduling functions, helping simplify setup and adjustment after installation in an electrical panel.
Manual Control
In addition to automatic scheduled operation, the timer provides manual control for situations where the connected circuit needs to be switched outside its programmed schedule.
This gives the user both automatic scheduling and direct control from the timer interface.
110VAC Supply
The AHC15A operates from a 110VAC, 50/60Hz power supply.
Verify the available supply voltage before installation.
16A / 250VAC Switching Contact
The timer's switching contact is rated 16A at 250VAC.
Actual allowable load depends on the electrical characteristics of the connected equipment.
Motor, transformer, ballast, LED driver, capacitive, and other inductive or electronic loads may have starting or inrush currents significantly higher than their normal operating current.
Always select the timer according to the actual connected load and applicable electrical requirements.
Power Failure Memory Reserve
The timer includes a reserve function of up to 15 days, helping preserve programmed settings during temporary power interruptions.
This feature is useful in scheduled systems where maintaining stored programming after a loss of supply power is important.
DIN Rail Installation
The timer uses a compact 2-module DIN rail format intended for compatible electrical control panels and enclosures.
DIN rail installation helps integrate the timer alongside contactors, relays, circuit protection devices, and other modular control components.
Installation Considerations
Before installation, verify:
- Available supply voltage
- Connected load voltage
- Load current
- Load type
- Switching characteristics
- DIN rail compatibility
- Enclosure requirements
- Applicable electrical codes
For higher-current, motor, or highly inductive loads, the timer may be used as part of a properly designed control circuit rather than directly switching the full equipment load.
Installation should be performed by qualified personnel familiar with electrical control systems.
