DOS45-44.4 放大器
FAST RESPONSE FOUR-QUADRANT 双极性 POWER AMPLIFIER 45V / 44.4A / 2kW
产品简介
DOS45-44.4 是松田精密（Matsusada Precision）DOS 系列的一款放大器，最大输出电压 45V，最大输出电流 44.4A，最大输出功率 2kW。
The DOS series is a four-quadrant bipolar amplifier featuring a high-speed response of DC to 200 kHz (CV mode). When combined with a function generator, it can output various waveforms, including sinusoidal, triangular, sawtooth, and rectangular waves. Since the DOS series amplifies external signals accurately, it is ideal for diverse simulation tests. It supports both sourcing and sinking operations in Constant Voltage (CV) and Constant Current (CC) modes. Despite its versatility and ultra-high-speed response, the unit remains compact. With high-visibility meters and user-friendly operation, the DOS series is an excellent choice for applications ranging from R&D laboratories to production lines.
Note: This product is not designed for charge and discharge of battery.
For battery charging and discharging applications, please refer to the Battery Cycle Tester product page.
Suitable for transient response test because of its ultra-high-speed response DC to 200 kHz and high power, maximum 2000 W.

功能特性
• 过压保护 (OVP)：DOS series is equipped with overvoltage protection, which protects load by limiting voltage up to approx. 110% of the rated output voltage even at abnormal conditions. * It is possible to set variable 0% to approx 110% output voltage range with -LVc option.
• 过流保护 (OCP)：DOS series is also equipped with overcurrent protection, which protects power supplies and load by limiting current up to approx 110% of the rated output current. * It is possible to set variable 0% to approx 110% output voltage range with -LCc option.
• High-speed Overcurrent Protection：The DOS series is provided with 2 types of overcurrent protections, high-speed overcurrent protection to limit the pulse current, and standard overcurrent protection to limit the static current. The standard overcurrent protection limits the static current, responding at around 1 msec. Additional high-speed overcurrent protection can limit the pulse current of square waveforms or from a capacitive
• Output Range：DOS series is a bipolar power supply that can perform four-quadrant operation. They can supply (source) and absorb (sink) current in the field of the drawing on the right.
• Rise Time：(Stepping time): The response time is sometimes described by the rise time (as shown in the drawing on the right). The rise time of an amplifier at a response speed of (= frequency bandwidth) Fc (Hz) is generally acquired by "tr ≒ 0.35/fc." Fall time tf is the same as tr. Frequency bandwidth: at 200 kHz or lower, tr = tf = around 1.8 μs, at 100 kHz or lower, tr = tf = around 3.5 μs
• Response Speed：Frequency response is the range of frequencies over which the amplifier can maintain its specified performance while amplifying the signal. This Figure: Output Amplitude Roll-Off vs. Frequency shows that as the input frequency increases, the amplifier can no longer follow the signal sufficiently, causing the output amplitude to decrease. In general, the point at which the output level drops by -3

• -LCc：Output Current Limit
The limit can be adjusted from 0% to approx. 110% using the front panel dial.
• -LF：Floating ground (withstand voltage 200 Vdc)
FAQ: What is floating ground?
• -LMsm: Master machine for master-slave control
-LMss: Slave machine for master-slave control：By connecting a master machine and a slave machine with dedicated control lines, the master machine can control
all slave machines at once. A parallel connection can increase the current that is insufficient for a single operation. Up to three units in total can be connected: one master unit and up to two slave units.
Note: Precautions for using the master-slave operation
Only master-slave connection is available for the same model.
In parallel operation, the frequency range is narrower.
It can also operate on a single.
Factory adjustment is required when changing the master-slave combination.
• -LN：Automatic Output Recovery
This option retains the output state when recovering from an input power interruption, such as toggling the AC power switch or a power failure. The user does not need to reset the protection status by manually cycling the OUTPUT switch.
Caution: If power is restored while the OUTPUT switch is set to ON, the unit will resume output immediately.
• -LPr：rms display
• -LVc：Output voltage limit
Variable from 0 to approx 110% with the dial on the front panel
• -L(220V)：200 Vac to 240 Vac ±10% single-phase, 50 Hz/60 Hz input
(150 W and 300 W models only)
