RP7900 系列再生电源

产品描述：
Keysight RP7900 系列再生电源可提供高达 30 kW 的电源和电力负载。这种双向电源非常适合用于测试储能和能量转换设备。大多数电子负载会将能量转化成热量散发出去，这会造成机架内的温度升高——进而导致测量结果出现误差。再生电源安全地将能量返回电网，消除了去除多余热量的额外成本。

Continuously source and sink current

The RP7900 can continuously sink up to 100% of its rated current indefinitely. The two-quadrant, bidirectional sourcing and sinking capability of the DC power supply allows for seamless, uninterrupted transitions between sourcing and sinking current without changing the power supply’s output characteristics or introducing any disruptive behavior.

Autoranging output – does the job of multiple power supplies

The RP7900 power supplies’ Autoranging output characteristic makes it much more flexible than rectangular or traditional output characteristic power supplies because they expand the power curve, giving the user more voltage and current combinations in one power supply. Power supplies with rectangular output characteristics provide full power at only one voltage and current combination. The RP7900 is like having many rectangular power supplies in one.

Emulate high-power battery

With its battery emulation feature, the RP7900 Series allows you to test your devices under the same power conditions that exist in actual use. Emulating the battery is key when characterizing battery operating life and detecting early product failures. Through programable resistance up to 394 Ω (model dependent), the RP7900 DC sources simulate the effects of the battery's internal resistance, enabling them to emulate the operation of batteries in different charge states. Use the bidirectional RP7900 as a power source or an electronic load, just like a battery.

Accelerate test throughput with industry-leading specifications

Shaving seconds or even milliseconds off a test time can lead to significant savings for high-volume manufacturers, making throughput gains a never-ending quest for test system designers. The RP7900 is a valuable tool for increasing throughput. It provides fast output speed, sub-millisecond commandprocessing time (≤ 1 ms), and an output list that can help you achieve significant throughput gains in your testing.

Accurately characterize your DUT’s power profile with advanced measurements

The RP7900 provides simultaneous voltage and current measurement capabilities that deliver high accuracy and resolution. Measurements can be made using two main modes: averaged or digitized. In average mode, the RP7900 delivers high-accuracy voltage and current measurements. The digitizing capability allows you to capture dynamic current or voltage profiles. In addition to high-accuracy voltage and current measurement capabilities, the RP7900 Series regenerative power system offers built-in power, peak power, amp-hour, and watt-hour calculations. These measurements help simplify your power efficiency and storage calculations.

Avoid damage to your DUT

When you are testing costly DUTs, integrating power protection measures into the test system is critical. Using instrumentation with built-in or integrated protection features provides a huge benefit when DUT protection is required. With protection measures implemented in hardware rather than test system software, error conditions can be detected and handled much faster, reducing the likelihood of the DUT sustaining major damage. The RP7900 provides built-in over-voltage, over-current, and over-temperature protection. For even greater DUT protection, use the accessory SD1000A Safety Disconnect System that was exclusively designed to work with the RP795x and RP796x Series to handle faults and ensure the output is secured with a redundant safety disconnect system.
