The NB141207-1HFA is a rugged weatherproof enclosure that is ideal for both indoor and outdoor applications. Constructed from molded halogen free self extinguishing fiberglass reinforced polyester (FRP), it is well suited for high temperature or corrosive environments. The integral mounting flange allows it to be wall mounted as well as on a flat surface without the need for extra mounting hardware. The fully gasketed lid features a stainless steel continuous hinge and stainless steel quick release latches with padlock hasps. The light grey color of the NB141207-1HFA is cleaner, cooler and aesthetically pleasing. Users can enjoy the physical benefits of better heat reflection and better UV resistance due to the lighter color. The contoured body provides an attractive and contemporary appearance.120 VAC Mounting Plate with Lightning ProtectionThe aluminum mounting plate features standard surge protected duplex 120 VAC outlets and a terminal block for easy hook up to the externally provided line power. In addition, the unit can accept up to two optional bulkhead-mount N-Type lightning protectors to protect the coaxial cable runs.Hot and Cold EnvironmentsTo 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 NB141207-1HFA includes a thermostat-controlled 200W heating system. The heater does not require the use of any of the AC outlets, leaving them all available for your equipment. No extra room for the heater is required since it is mounted underneath the plate.For cooling, the thermostat-controlled 12W high airflow, low noise fan allows air to be pushed or pulled through the enclosure. Filters for both ports are easily removable for cleaning and replacement. Like the heater, the cooling fan does not require the use of any of the AC outlets, leaving them all available for your equipment.User Adjustable ThermostatThe 1HFA series features an adjustable thermostat that incorporates two separate thermostats, allowing the independent control of heating and cooling. The thermostat provides a temperature range of +32°F to +140°F for both the heating and cooling systems.The heat thermostat features a Normally Closed (NC) circuit. When the temperature rises to the temperature set on the heat adjustment dial the circuit opens which turns off the heater. When the temperature falls below the temperature set on the heat adjustment dial the circuit closes which turns on the heater.The cooling thermostat features a Normally Open (NO) circuit. When the temperature rises to the temperature set on the cooling adjustment dial the circuit closes which turns on the cooling fan. When the temperature falls below the temperature set on the cooling adjustment dial the circuit opens which turns off the cooling fan.Heater Setting Range Cooling Fan Setting Range NC - Open On Rise +32°F to +140°F NO - Close On Rise +32°F to +140°F Switching Difference: 12°F ±7°F tolerance<<<<<< Warning >>>>>> Recommended Temperature Setting for the Heater Portion of the thermostat should only be between 32º to 50ºF Recommended Temperature Setting for the Fan Portion of the thermostat should only be between 80º to 120ºF Setting the Heater setting too high and the Fan setting too low can result in a conflict between the two halves wherein the unit might try to continue to heat while simultaneously trying to cool it.
