Outdoor Cooler Translation

As advanced communication networks develop, network systems are present everywhere outdoors. The outdoor cubicle model reliably protects the internal equipment even under severe conditions such as sun exposure, wind, rain, and dust. Furthermore, by adopting low-noise sirocco fans proven in building air conditioners and multi-stage control tailored to the air conditioning load, we have achieved the industry’s top-class ultra-low noise level of 40dB (KCD-10-1).

High Waterproof Performance

• JISC0920 Protection class 4 or higher.
• No harmful water leakage at wind speeds of 20m/s and water flow of 4L/m2 · min.
• No harmful damage or breakage at wind speeds of 40m/s.

Excellent Environmental Resistance

• The exterior panel uses highly corrosion-resistant hot-dip galvanized steel sheet with a heavy anti-salt damage coating.
• The heat exchanger on the heat dissipation side uses aluminum fins treated for corrosion resistance and further coated with urethane resin. Achieves rust prevention performance of 1000 hours or more in the salt spray test (JISC5400).

Compliant with NTT-TR (KCD-10/20).

• Enables reliable temperature management without interfering with advanced network equipment.
• Measurement of radiated disturbance waves (TR55004 and VCCI CLASS B)
• Measurement of power line conducted disturbance waves (TR55004 and VCCI CLASS B)
• Radiated immunity test (TR 549001) (IEC 61000-4-3)
• Conducted immunity test (TR 549001) (IEC 61000-4-3)
• Electrical Fast Transient test (EFT/B) (TR 549001) (IEC 61000-4-2)
• Electrostatic discharge test (ESD test) (TR 549001) (IEC 61000-4-2)
• Lightning surge application test (TR 189001) (IEC 61000-4-5)

Features List (Available features vary by model)

Maintenance Notification Function	Refrigerant Pressure Abnormality Alarm	Temperature Sensor Abnormality Alarm	Panel Internal Temperature Abnormality Display	Overload Protection Device
Displays a filter check output signal at set intervals.	If the refrigerant pressure rises due to filter clogging or other issues, the unit stops abnormally and the alarm contact is activated.	The unit stops and the alarm contact is activated if there is an abnormality in the panel internal temperature sensor or the evaporator temperature sensor.	An abnormality is displayed if the panel internal temperature reaches the set temperature plus $10^\circ\text{C}$ or higher.	If the compressor continues to operate under an overload condition, the protection device automatically stops the compressor.
Outdoor Specification	Inverter Control	Self-Diagnosis Function	Low Noise	DC 48V Compatibility
A cooler for outdoor control panel cooling.	Energy saving is achieved through inverter control.	Added more detailed diagnostic functions when an error occurs.	Industry-leading low noise achieved through the adoption of sirocco fans.	Can handle a wide range of voltage fluctuations (-40 ~  -59V).
