EZD650V-1000W 电子负载
Multi-Function DC Electronic Loads 650V / 50A / 1kW
产品简介
EZD650V-1000W 是松田精密（Matsusada Precision）EZD 系列的一款电子负载，最大输出电压 650V，最大输出电流 50A，最大输出功率 1kW。
The EZD series is a high-performance, multi-function DC electronic load designed for a wide range of testing applications. Featuring seven distinct load modes, including CC, CR, CP, and CV, it offers exceptional flexibility for evaluating power supplies, batteries, and other electronic components. With advanced functions like high-speed sequencing and switching, the EZD series provides precise and repeatable results. Its master-slave capability allows for easy expansion up to 9 kW, making it a scalable solution for both R&D and production environments. Built with Matsusada Precision's commitment to quality, this series delivers the reliability and performance you expect from a product made in Japan.
The EZD series is ideal for simulating dynamic load conditions to test the transient response of power supplies. The high-speed switching function allows for precise evaluation of voltage stability under fluctuating loads.
Suitable for evaluating battery capacity and discharge characteristics. The constant current (CC) and constant power (CP) modes allow for accurate simulation of real-world discharge cycles to determine battery performance and lifespan.

功能特性
• Multi operation mode：EZD series is available with the following seven operation modes. Constant Current (CC) mode Constant Resistance (CR) mode Constant Power (CP) mode Constant Voltage (CV) mode CC mode + CV mode CR mode + CV mode CP mode + CV mode
• Switching mode：This mode allows for periodic switching between user-defined upper and lower setpoints. The function is available in CC, CR, CP, and CV modes.
• Note: Setting：Upper and Lower Limits Setting ranges for upper and lower limits vary depending on the selected operation mode. (The lower limit must be set to a value strictly lower than the upper limit.) Frequency Setting range: 1 Hz to 4 kHz Setting resolution: 0.1 Hz Duty ratio Setting range: 5% to 95% Setting resolution: 0.1% Slew rate (in CC mode) Model Range Setting range Setting resolution EZ650V-1000W H
• Master-Slave Control：In the EZD series, the operations of up to five units are performed as a single system as long as these types have the same rated voltage. (The series requires optional dedicated cables for the connection.) The master unit indicates the total values that are obtained from the connected units setting and monitoring as setting and monitoring values. In order to gain the highest load power up to 9 kW
• All five Model EZD650V-1000W units：Total load power of 5 kW.
• A Model EZD650V-1000W unit and four Model EZD650V-2000WB units：Total load power of 9 kW.
• Sequential control：EZD series has two types of sequential control. They are available in CC, CR, CP, and CV modes. The pattern is readily created through the front panel and the exclusive software. The program can save two patterns of the fast sequence as well as 10 patterns of the normal sequence at maximum in the EZD unit, and can also be recalled at any time.
• Fast sequence：This function executes a sequence of predefined steps, each with a fixed duration. The setting is available with 1,024 steps at maximum. Repeat count: 1 to 10000 times or infinity Setting range: 10 µs to 1000 ms Setting resolution: 100 µs
