Power It Up: CP10 EtherCAT-Capable Power Supplies From PULS

PULS has released three power supplies with EtherCAT capabilities and other functions not commonly found in other available products. These power supplies are intended for industrial control, process control, and monitoring and measurement equipment.

An electrical power supply is a crucial device that transforms electrical current from a source into the proper voltage, current, and frequency necessary to operate the components on the output side. The power supply ensures the device receives the accurate electrical energy required for its correct and efficient operation.

Specifically, the CP10 models are designed to accept input voltage from either AC or DC sources. The AC input voltage can range from 100 to 240 volts with a tolerance of -15% to +10%, while the DC input voltage can vary from 110 to 150 volts with a tolerance of ± 20%.

The versatile power supplies can produce various output voltages. PULS offers the CP10 series with an adjustment range of 24 to 28 volts with either 10 (CP10.241-ETC) or 20 amps (CP20.241-ETC) or 48 volts with ten amps (CP20.481-ETC), depending on the model. In addition, the PULS power supplies are equipped with active harmonic correction capabilities, which effectively work to minimize or eliminate harmonic distortion. This feature contributes to the efficiency of the electrical system.

CP10 Series Functions

The power supplies in the CP10 series offer different user assistance features, including an EtherCAT interface. The power supply's EtherCAT feature allows users to access data and control certain aspects of the power supply. EtherCAT provides access to real-time and recorded data on the condition of the power supply and the power line, making preventative maintenance and troubleshooting simple. Configuration via EtherCAT is also simple. PULS provides quick startup guides, making it easy to set up even for someone new to programming.

Many available signals exist, including DC OK, alarm signals, a digital ON/OFF function, and a single/parallel use mode. The single/parallel use mode is ideal for load sharing between power supplies connected in parallel to give redundancy for higher system availability and to increase output power. With this redundancy, if one device fails, the other could support the load current without interruption or maintenance. However, with multiple devices, an increase in harmonics is expected. It’s also necessary to note that if three units are placed in parallel, a fuse or circuit breaker is required on each output (check the datasheet for specifications regarding amperage).

The PULS power supplies also include a standard power-boost function across the CP10 series. This feature enables the power supply to reserve up to 20% of its capacity. The function can operate in temperatures up to 45°C. Moreover, the power supplies can deliver three times the nominal output current for 12 ms to ensure that fuses work correctly.
