Chroma 62000L系列可编程DC电源具有低噪声线性性能和快速瞬态响应。这些单元具有许多独特的功能，这些功能针对整体自动化测试系统集成，汽车电动电子设备MCU/ECU，功率半导体，无线通信等。62000L系列是高质量但具有成本效益的可编程DC来源，旨在满足严格的功能下一代电力电子设备的要求。
The GPIB and USB control interfaces come standard with the 62000L Series, no additional purchase required. The 62000L Series can be easily remote controlled via either of these two interfaces. The 62000L weighs less than 2.5 kg, and its case measures 214.6W * 88.6H * 280D mm. Its light weight and compact size makes it easy to handle and stack safely.
Auto-ranging allows you to freely adjust voltage and current. This feature eliminates the need to manually select the optimum range allowing all of the power to be available across all of the voltage and current settings.
If there are applications that need voltages and currents greater than the rated maximum outputs, this can be achieved using multiple power supplies. The power supply can output an extended range of voltages or currents by connecting more units. Up to 7 units can be connected at the same time, using a series-parallel connection to achieve greater voltage (up to 252V) and current (up to 49A) output.
62000L Features and Applications
Autoranging Output
 ▲ Autoranging Output |
The 62000L Series Programmable DC power supplies have wide operating ranges. Chroma's model 62015L-60-6 for example, the output specification 150W/60V/6A can operate under different combinations as the figure shows below while other common DC power supplies can only achieve the maximum output power of a single point. For wide range voltage and current applications, one DC power supply can be used to test the input of both low voltage/high current and high voltage/low current UUTs. When integrated into a standard ATE, one 62000L Series DC power supply can replace multiple DC power supplies to significantly reduce cost and save space. |
High Transient Response
 ▲ High Transient Response |
The 62000L Series features the state-of-the-art DC power supply design with high transient response for output voltage. Take the model 62010L-36-7 for example, when the output current changes from 3.5A to 7A at the speed of 1A/us, the voltage change of actual output can return to 15mV within 10.1us. For dynamic load change, the 62000L Series can quickly react in order to give a stable DC output, as well as reducing the surge voltage generated by load change that could damage the UUT. As to non-static products or test applications, the 62000L Series can timely provide a stable DC power supply. |
Low output Noise
 ▲ Low output Noise |
The 62000L Series provides pure and stable DC power. For example, the 62010L-36-7 output voltage noise is 1.18mVp-p (20~20MHz) under the maximum rated current and maximum output power. For precision products that require strict power quality, such as semiconductor testing and IC drive, the 62000L Series is able to comply with the product specification to protect the UUT from the interference of heavy noise providing low ripple and low noise input power with pure quality. |
Auto Sequencing Programming
 ▲ Auto Sequencing Mode |
The auto sequencing programming function built into the 62000L Series allows the user to define and edit the output waveforms and cycles desired. Using 8 steps per cycle, each step can set the time for voltage to rise or fall as well as to dwell. This function can also be applied to the waveform signal simulation test of power electronics and the power simulation test of automotive electronics by editing the required output voltages following the UUT test criteria. |
Master-Slave Control
The 62000L Series master-slave control has 4 modes listed as follows:
- Parallel mode: The master-slave parallel control connects multiple power supplies to extend the current output.
- Series mode: The master-slave series control connects multiple power supplies to extend the voltage output.
- Normal mode：Master-Slave正常控件遵循每个电源为主的输出设置的延迟时间。
- Track mode: The master-slave track mode tracks each power supply to synchronize with the output voltage and status of master.
