The HW-N18-1HFS enclosure is a rugged, larger sized (18″ x 16″ x 8″) weatherproof enclosure that is ideal for both indoor and outdoor applications. Constructed from molded fiberglass, it is well suited for high temperature or corrosive environments. The mounting flange allows it to be wall mounted as well as on a flat surface. The box can also be pole mounted with the optional pole mounting hardware kit. The fully gasketed lid features a stainless steel continuous hinge and stainless steel quick release latches with padlock hasps. The enclosure material is UV stabilized and comes in machine tool gray.


The HW-N18-1HFS is ideal for custom applications, which may require special modifications to the enclosure. Mounting stand-offs inside the enclosure can be used for mounting plates.


Mounting Plate


The plate features four standard surge protected 120 VAC outlets and a terminal strip to supply power to internal equipment.


Hot and Cold Environments


To help ensure trouble-free operation of electronic equipment, proper operating temperatures inside an enclosure needs to be maintained. With the built-in Heater and Cooling system, internal temperatures can be better maintained. This model is ideal in Hot and Cold environments.


The HW-N18-1HFS comes with two 120 VAC 200 watt (400W total) heating elements and two 120 VAC 12W (24W total) cooling fans. The fans and heaters are controlled by HyperLink’s exclusive solid state temperature controller. The standard unit has a fan turn-on temperature of +93° F and a heat turn-on temperature of +16° F. The controller features improved temperature setpoint accuracy and can be factory modified for other temperature setpoints. The heater and fan are controlled by two integral high current solid state AC relays. The relays feature Zero Cross Detection for EMI reduction. No extra room for the controller is required since it is mounted underneath the plate. (A minimum order quantity is required for custom fan Setpoints and other configurations.


The HW-N18-1HFS includes two thermostat-controlled 12W (24W total) fans. The high airflow, low noise fans used allows air to be pushed or pulled through the enclosure. Filters for both ports are easily removable for cleaning and replacement. The fans turns on when the internal temperature rises to 120° F (49° C) ±5° and turns off at 90° F (32° C) ±10°. These cooling fans do not require the use of any of the AC outlets, leaving them all available for your equipment.


Lightning Protection


Surge protection is provided as a standard feature on the internal AC outlets. In addition, the unit can accept up to two optional bulkhead-mount N-Type lightning protectors to protect the coaxial cable runs.
