DOA75-1 放大器
FOUR-QUADRANT 双极性 AMPLIFIER 75V / 1A / 75W
产品简介
DOA75-1 是松田精密（Matsusada Precision）DOA 系列的一款放大器，最大输出电压 75V，最大输出电流 1A，最大输出功率 75W。
The DOA series is a four-quadrant bipolar amplifier featuring wide bandwidth and ultra-high-speed response from DC to 1 MHz.
It is ideal for transient response testing, effectively utilizing its high-speed characteristics. Capable of operating as both a DC power supply and an electronic load, it can drive various loads, including inductive loads such as transformers, capacitive loads such as capacitors, and piezoelectric elements.
This versatile series delivers maximum current even at DC output.
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.
核心参数
• 最大输出电压：±75 V
• 电流：±1 A
• 功率：75 W
• 输入电压：100 to 240 Vac, 50/60 Hz, Single-phase
• 输出控制：[External control signal] Vcon-in, Input voltage -3 to +3 V
[Front panel] DC bias: 10-turn potentiometer with -100% to +100% setting
功能特性
• 过压保护 (OVP)：Equipped with overvoltage protection, this unit limits the output voltage to approximately 110% of the rating, protecting the load during fault conditions.
• 过流保护 (OCP)：Equipped with overcurrent protection, this unit limits the output current to approximately 110% of the rating, protecting both the power supply and the load during overload.
• High-speed Overcurrent Protection：This unit features two types of overcurrent protection: a high-speed circuit to limit pulse currents and a standard circuit for static currents. The standard protection limits continuous currents with a response speed of approximately 1 ms. The high-speed protection circuit limits pulse currents (e.g., square waves or capacitive loads) to approximately twice the rated current.
• Output Range：This unit is a bipolar power supply that is possible to operate in four-quadrant behavior. It is able to source or sink current in the ranges as shown in the following figure.

选件 / 附件
• -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.
This eliminates the need to manually reset the protection status or turn the OUTPUT switch off and on again.
Caution: If the power is turned on while the OUTPUT switch is set to ON, the unit will output voltage immediately.
• -LVs：The output range is shifted
Shifting following 3 ranges is possible for ±75 V output models.
(L) -125 V to +25 V
• Shifting following 3 ranges is possible for ±150 V output models.：(L) -250 V to +50 V
• 交流输入电缆：Standard
