Corso launches free air convection cooling open frame power supply with 200% peak power for industrial applications

Cosel announced the addition of 150W and 300W free air convection cooling power supplies LHP150F and LHP300F, which are specially designed for industrial applications that require a high level of safety and have passed EN62477-1 (OVC Ⅲ) certification. The normal operating input voltage range of LHP150F and LHP300F is 85VAC to 264VAC, and the typical efficiency rating is as high as 93%. It provides five different output voltages commonly used in industrial automation processes, and can provide 200% peak power for dynamic loads for up to 10 seconds. The standard product is an open frame PCB type, with an optional chassis and cover.

Industrial applications require high-efficiency power supplies that can work with high safety levels in various environments. LHP150F and LHP300F have passed EN62477-1 overvoltage category III (OVC Ⅲ) certification, which means that the final equipment powered by this product can be directly connected to the main switchboard without additional isolation. This simplifies the task of system designers, reduces costs, and maintains efficiency at the highest level.

The LHP150F and LHP300F are designed for global applications, with an input voltage of 85 to 264VAC and five different output voltages: 24V, 30V, 36V, 42V and 48V. The output currents of LHP150F are 6.3A, 5.0A, 4.2A, 3.6A and 3.2A respectively, and the output currents of LHP300F are 12.5A, 10.0A, 8.4A, 7.2A and 6.3A respectively. The output voltage of both products can be adjusted using the built-in potentiometer.

Industrial applications usually require higher currents during start-up or peak operation.

The design of LHP150F and LHP300F has a high dynamic control level and a power level that can withstand long-term peak loads. When a peak load situation occurs, 200% of the rated power can be provided for up to 10 seconds. For example, the LHP150F 24V output version provides a stable current of 6.3A and a peak current of 12.6A. The same ratio applies to all versions of LHP150F and LHP300F.

For low harmonic current distortion, LHP150F and LHP300F use active power factor correctors (PFC), the conversion stage uses LLC resonant topology, combined with the latest generation of power semiconductors, the typical efficiency can reach 94%.

Optimized for convection cooling, it can operate in an ambient temperature range of -10°C to +70°C. Depending on the assembly method and ventilation of the final device, derating may be required in accordance with the regulations in the technical documentation.

The open frame size of LHP150F is 75×27×160 mm (2.95×1.07×6.30 inches), and the maximum weight is 320 grams. The open frame size of LHP300F is 84×37×180 mm (3.31×1.46×7.09 inches), and the weight The maximum is 580 grams.

LHP150F and LHP300F have 3,000VAC input to output, 2,000VAC input to ground (FG) and 500VAC output to ground (FG) insulation voltage, as well as built-in surge, overcurrent and overvoltage protection circuits.

Both power supplies meet the safety requirements of UL (USA), C-UL (Canada), DEMKO (Denmark) and TUV (Germany), and have passed UL62368-1, EN62368-1, EN62477-1 (OVC III) certifications, And in line with DEN-AN.

The attention to versatility and detail meets the requirements of specific applications, providing customers with a variety of options, including coating (C), low leakage current (G), EP connector type (J4), remote on/off ( R), base (S), shell (SN), junction box type (T), external capacitor bank connector (U1), output 8-pin connector (LHP300 only) (J5), in-line wiring board ( T4) and built-in DC fuse (DC).

The LHP150F and LHP300F series have a five-year warranty and comply with European RoHS, REACH and Low Voltage Directives.
