The DTS3031A115N3LG is a 115 V outdoor air conditioner from the DTS Series, built for side mounting on an enclosure surface where high capacity system cooling is required. It suits panel builders, electricians and OEM engineers who need to hold electrical and electronic equipment at a controlled temperature inside an outdoor-rated cabinet.
Cooling is closed loop, so clean enclosure air is recirculated without ever mixing with contaminated ambient air. The unit delivers 1194 BTU/h (350 Watts) at +95/+95 F (+35/+35 C) using R134a refrigerant with a 145 g charge. Internal air capacity is 37 CFM and external air capacity is 99 CFM (unrestricted), with a noise level under 64 db. An expansion valve prevents evaporator freeze up while minimizing heavy inrush currents.
Electrically, the DTS3031A115N3LG is rated 115 V 60 Hz with an operating range of 103-127 V, 243 W power consumption, 2.1 A running current and a starting current of 10. It is supplied with a line cord with plug. The thermostat is accessible from inside the enclosure and adjusts from +50F to 104F (+10C to +40C), factory set at +95F/+35C.
The case is galvanized sheet metal finished in RAL7035 light gray, measuring 15.50 in H x 7.00 in W x 7.75 in D (394 x 178 x 197 mm) and weighing 30 lbs (13.6 kg). It carries UL, cUL and CE approvals and complies with IP56 and NEMA 3R, 4. Condensate discharges directly through a 1/4" NPT threaded port, and a washable aluminum mesh filter protects the condenser.
A gasket, mounting kit and template for the enclosure cutout and drilling are included, and a door contact provision lets the unit power down when the enclosure door is opened. Rated for ambient temperatures from +46F (+8C) to +114F (+45C).
