2. Introduction

The TC06-70ZEH/01 air conditioner is a cooling product developed for telecom industry where the AC power supply is lack. This air conditioner is powered by -48VDC. This air conditioner’s frequency can be regulated. It has cooling capacity regulating function, and the fans can regulate speed automatically to reduce noise.

The internal cycle air path absorbs the hot air from the upside, and discharges the cold air from the downside of the air conditioner. The external cycle air path absorbs the external cold air from the downside, and discharges the hot air from the upside after heat exchange.

3. Features

(1) This DC48V variable frequency air conditioner can be widely used for outdoor communication cabinets, battery cabinets, electric cabinets and industry control cabinets, BTS cabinet, telecom power cabinet, etc.

(2) The protective level of internal and external circulation is IP55, which can protect cabinet to avoid moisture, dust, water. The air conditioner can also be indoor or outdoor installed.

(3) R134a system.

(4) Digital temperature controller and high precision of temperature control.
