EW150V-1200W 电子负载
HIGH POWER 直流 ELECTRONIC LOAD 150V / 240A / 1.2kW
产品简介
EW150V-1200W 是松田精密（Matsusada Precision）EW 系列的一款电子负载，最大输出电压 150V，最大输出电流 240A，最大输出功率 1.2kW。
The EW Series is a compact 3U high-power DC electronic load delivering up to 2400W. With four operating modes-CC, CR, CP, and CV-it also offers fast transient testing through a dynamic mode and automated multi-step sequences.
Its large LCD provides clear monitoring of voltage, current, and power, while USB memory enables simple data logging and sequence management. Scalable up to 12kW with booster units, the EW Series is an ideal solution for testing DC-DC converters, batteries, and solar cells-combining high performance, ease of use, and trusted Japanese quality.

功能特性
• 1.6 Times More Load Power Than Conventional Models：1.5kW in the previous model 2.4kW
• Constant Current (CC) Discharge：A set current is discharged. Even if the terminal voltage changes during discharge, a constant current can flow.
• Constant Resistance (CR) Discharge：A set resistance is used to discharge. The discharge current value is determined according to the set value by measuring the terminal voltage value.
• Constant Power (CP) Discharge：A set power value is used to discharge. If the terminal voltage changes during discharge, a certain amount of power can be consumed according to the change.
• Constant Voltage (CV) Discharge：A set voltage value is used to discharge. Even if the terminal current changes during discharge, it can be operated at a constant voltage.
• Auto switching between operating modes：With the auto-switching, the operating mode where the load current is minimized is automatically set in response to the set value. The individual function of CC+CV mode, CR+CV mode, and CP+CV mode using the auto-switching remains as it is.
• Switching Mode：This mode allows you to periodically switch between two values. It is available in CC mode, CR mode, CP mode, and CV mode. Slew rate (in CC mode, Range H) at 10 V or more and at an input of 30% or more of the rated current, with no voltage drop due to wiring [EW150V-1200W] 16 A/μs to 0.5 mA/μs, setting resolution 0.5 mA/μs [EW150V-2400W] 32 A/μs to 1 mA/μs, setting resolution 1 mA/μs Frequency 0.1

选件 / 附件
• -LGob *：Optical Interface port
This option changes the standard interfaces to a built-in optical interface port. By combining this option with an adapter for optical connection (sold separately), communication between the control device and the power supply can be controlled in an isolated state. Be sure to select this option when using the product in the following environments.
-LGob: Optical interface port + optical cable 2 meters
-LGob(Fc5): Optical interface port + optical cable 5 meters
-LGob(Fc10): Optical interface port + optical cable 10 meters
-LGob(Fc20): Optical interface port + optical cable 20 meters
-LGob(Fc40): Optical interface port + optical cable 40 meters
Select the optional optical interface port (-LGob) when using this DC Electronic Load under the following conditions.
Noisy environments such as factories (example: when motors or coils are used near loads or power sources).
If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
When there is a possibility of arcing or output short-circuit.
Optical isolation adapter is required.
• -LRs *：RS-232C/RS-485 interface port
Using RS-232C/RS-485 communications, output controlling and operation status monitoring of these devices can be provided.
• EW-MS cable 1 meter：Dedicated cable for controlling booster
The cable is used for the primary unit controlling the boosters (replicas).
The cable is required for one booster. You can substitute it with a commercially available LAN cable.
• 光隔离适配器：To use the optical interface, you need to prepare an optical interface adapter separately. The following interface adapters are available according to your controller port.
CO-E32 : LAN to optical interface adapter
USB-OPT : USB to optical interface adapter
CO-OPT2-9 : RS-232C (9 pin) to optical interface adapter
CO-OPT2-25 : RS-232C (25 pin) to optical interface adapter
CO-OPT4-25 : RS-485 (25 pin) to optical interface adapter
CO-G32 : GPIB to optical interface adapter (Scheduled for discontinuation in December 2028)
Example of communication with optical fiber
