CNS650-M Series AC/DC Power Supplies

CNS650-M Series AC/DC Power Supplies

Artesyn Embedded Technologies' CNS650-M series 650 W AC/DC power supplies feature a wide input range and single output

 Artesyn Embedded Technologies CNS650-MU series of single output open-frame AC/DC power supplies are offered in 12 V, 24 V, or 48 V outputs with +15% trim range. Each power supply comes with a 12 V fan output and 5 V standby. All models feature ITE and medical safety approvals and accept a universal input of 90 VAC to 264 VAC. Depending on operating conditions, its 4'' x 6'' x 1.54'' compact and high-density, U-channel construction delivers up to 400 W of output power with free air convection cooling and up to 650 W with 400 LFM of forced air.

The CNS650-M is equipped with an I2C interface available with industry-standard PMBus™ communications protocol. These power supplies are ideal for industrial systems as well as for medical applications. The CNS650-M series power supplies can be stored or shipped at temperatures from -40°C to +85°C and relative humidity from 5% to 95% non-condensing. When the main output is shorted, the output will go to hiccup mode. Recovery will be automatic when the short is removed. The 5 V standby will remain on while the 12 V fan output is off. A short circuit on the 5 V standby will shut down the entire power supply. The power supply will auto recover once the fault condition ceases to exist.

When the main output is shorted, the output will go to hiccup mode. Recovery will be automatic when the short is removed.

Overtemperature Protection (OTP)
The power supply will be internally protected against overtemperature conditions. There will be three overtemperature protection sensors: on the main output, the PFC circuit, and the standby output. When one of the sensing circuits has reached the OTP limit, all outputs, except standby, will shut down and will remain off until the overtemperature condition no longer exists. A suitable hysteresis point between the OTP threshold and the recovery point will be set to ensure there is no frequent on-off cycling of the outputs. The temperature recovery point will be set well within the operating temperature range. Upon reaching the temperature recovery point, all outputs will auto-recover.

EMI Emissions
The CNS650-M series have been designed to comply with the Class B limits per requirements of EN55022 (FCC Part 15) and CISPR 22 (EN55022) for emissions. The unit is tested with Class I input (PE connected) at 650 W full load using resistive load with airflow.

Conducted Emission
The CNS650-M power supplies have internal EMI filters to ensure the power supplies' conducted EMI levels comply with EN55022 (FCC Part 15) and EN55022 (CISPR 22) Class B limits.

Short Circuit Protection (SCP)
The CNS650-M power supplies will withstand a continuous short circuit with no permanent damage, applied to its main output during start-up or while running.
