MDTThe MDT-1 is a 100% DIGITAL Lighting & recycling timer

Precision repeat cycle timer with a 24-hour timeclock to control HID lighting and hydroponic pump. Can control up to 15A directly. Hi-temperature protection disables the HID lights if the temp inside the growing area gets too hot. Hot-start prevention disables the HIDs in the event of a power failure. The HIDs restart after they have cooled down.

• Coordinates 2 main timing functions in one convenient package.

• Control lighting schedules with 24-hour time clock.

• Integrated digital recycling timer can operate daytime, night time or 24 hours a day.

• Digital recycling ON & OFF times can be pro grammed in hours, minutes and seconds.

• HI-Temp shutdown feature allows the user to set a maximum temperature. In the event of overheating, the MDT-1 will shut off the lighting. If overheating event happens, the unit logs the max temperature and the time it occurred.

• Hot start prevention monitors the incoming power and will disable the HID lights in the event of a power failure. After a user selectable delay, the HID lamps are permitted to re-start.

• MDT-1 also features 15 amp resettable circuit breaker.

The HID-2 HID Lighting Controller is the simplest and BEST lighting controller you can buy.

The HID-2 has many features including a 24-hour DIGITAL time-clock that is extremely accurate and EASY to use. It has a battery backup to ensure continued function even after power outages. 

Tha HID-2 comes with a remote temperature sensor that detects unsafe temperatures and will activate the "Hi-temp shutdown" feature if air temperature rises above the adjustable setpoint that the user selects. This feature will protect plants from overheating by disabling HID lights in the event of a ventilation or cooling failure.

The "Hot-start" prevention feature ensures that your HID lamps will cool properly before re-firing in the event power is momentarilly turned off.

The HID-2 also has the ability to stagger-start 2 separate lighting banks with an adjustable time delay to eliminate large power spikes. Or if the user chooses, the second output can be selected to be a NIGHT only output.

The HID-2 is extremely easy to use and reliable. Another great product from Sentinel - Global Product Solutions.

When trying to remotely control large amperage equipment such as air conditioners or heavy-duty fans, you need a device  like the HAC-30A. The HAC-30A makes it simple to control up to 30-amp @ 240 volt devices from a single timer or controller.

 An internal heavy-duty relay inside the HAC-30 is turned On and Off by  connecting the 15 ft "trigger cable" to any 120volt controller like the EVC or CHHC. When the controller turns ON, the trigger cable caries the voltage to the relay inside the HAC-30A, the relay activates,  and the device connected to the HAC-30A is energized. Think of the HAC as a remote high amperage switch.

The HAC-30A is housed in a sealed, aluminum heat sink enclosure and can be mounted using the wall mount bracket included. The user must connect a 240 volt, up to 30 amp circuit to the HAC-30A.            

* Some simple wiring is required.
