Chroma has released its next-generation bidirectional DC power supply, model 62450D-2000HL, which delivers a single-unit power density of 45kW in a 4U high form factor.
The company reports that the 62450D-2000HL enables one-key switching between two output ranges within a single unit, effectively providing the output range of two units in one. Users can switch between the high voltage – 2000V/±60A/±45kW – and high current – 650V/±180A/±45kW – range with a single touch, offering up to an 8x wider output range to meet diverse testing needs for devices under test – DUT.
The innovative design integrates two output ranges in a single unit, enabling seamless switching and eliminating the need for different equipment for various DUT specifications. For example, bidirectional on-board chargers – BOBC – typically have power ratings of 11kW and 22kW; battery platforms incorporate 400V and 800V; and AC-DC charger modules are trending towards higher power. Previously, separate bidirectional power supply equipment was necessary for high voltage and high current applications. Now, Chroma’s model effectively acts as two units in one with its dual-output range capability, helping users save space and cost while improving equipment utilization.
The dual output range can be switched with a single touch on the front panel touchscreen or remotely via a command. In automated test equipment – ATE – production lines, this allows dual-range operation by using the switch command to select between High and Low output ranges without needing manual disconnection or reconnection at terminals.
The next-generation bidirectional DC power supply not only sets an industry benchmark with its single-unit power density but can also be paralleled in master-slave configurations to achieve even higher power levels. The unit’s reported bidirectional conversion efficiency is at 94%, reducing heat loss significantly during factory operations. It efficiently recycles electrical energy back to the grid during load operation contributing to energy saving goals.
Inheriting user-friendly features from previous models like Source & Load mode support along with advanced battery simulation – standard – solar array simulation – optional – it is compatible with Chroma’s SoftPanel software for remote operation.
