EA Elektro-Automatik PSB9200-70 Bi-Directional DC Power Supply
The Elektro-Automatik PSB9200-70 is an advanced microprocessor-controlled bi-directional power supply that integrates two essential functions in one unit: a power supply (source) and an electronic load (sink) featuring energy recovery capabilities. This unique configuration allows for robust two-quadrant operation, making it an ideal solution for various applications.
The internal electronic load is designed to effectively manage and discharge the capacitance found at the DC terminals, ensuring high voltage dynamics that are crucial for precise operations. Each model includes an active Power Factor Correction (PFC) circuit, thus optimizing energy efficiency. The device is engineered for compatibility with both two- and three-phase power supplies, with typical voltage ratings ranging from 380 V to 480 V AC. For specific applications, 208 V AC models can be provided at a 50% derated power level.
One of the standout features of the Elektro-Automatik PSB9200-70 is its flexible autoranging bidirectional power stage, which allows it to provide a higher output voltage at lower current or a higher output current at lower voltage, adaptable up to the maximum rated output power. This feature applies equally to sink mode operations, greatly expanding its versatility.
The power set value is adjustable across a broad application spectrum using this singular device. It includes a user-friendly color TFT touchscreen that simplifies operation—allowing users to control all functions with a mere fingertip. Additionally, users can set voltage, current, power, or resistance values easily through the rotary knobs or by entering them directly via the numeric pad.
