High Power Relay - Climate Control/Co2/AC

HAR-1 Relay
This power relay uses high amperage capacity contacts to transfer power to large fans, pumps or lighting systems requiring high voltage or amperage service. Prevents premature failure of equipment, timers or other switching controls due to excessive current draw. Allows switching of 240 VAC equipment with 115 VAC controls. Prevents equipment overheating due to insufficient power supply. Use the HAR-1 to operate 115 or 240 volt high draw equipment. Provides 30 amp switching capacity with 115 VAC trigger input from control device. Approved for indoor use only.

If you are unsure of proper installation consult a certified electrician or the equipment manufacturer for detailed instructions.

Power Expander 240V 30A Sequential

PWX Power Expanders allow you to turn on more high powered loads (such as horticultural lamps) from a timer or environmental controller. Usually the electrical outlet for your timer or controller can only service a single 1000w lamp without tripping the circuit breaker. By utilizing other outlets (on separate circuit breakers) more lamps can be added and still be controlled by your timer. These Power Expanders have ready to go outlets (120V or 240V depending on model), a 10ft trigger cord (that sends a low power turn-on signal from the timer or controller) and a power cord that plugs into the outlet on the separate circuit breaker. Multiple Power Expanders can be used to control a large number of devices.

The PWX-240 and PWX-240S (not pictured) Power Expanders are similar to the PWX-1 except they control 240V devices. The Power Cord connects to a 240V 30A service. The trigger cord has a 120V plug. This lets a 120V controller operate 240V lamps. There are six 240V outlets allowing control of up to six 1000W lamps. The PWX-240 turns all outlets on at once. The PWX-240S sequences two outlets on, 20 seconds later the next two, and 20 seconds later the final two. This allows time for the start-up current surge ("inrush") of two lamps to finish before the next two create their inrush current. This reduces circuit breaker tripping and other electrical problems.

Sentinel HAC30A HiAerage Controller

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.
