A power amplifier capable of outputting ±200V from DC to 20kHz. It supports a wide range of applications, including power supply environment testing, precise electrical measurements, and driving special loads.
The 4500 series is a wideband, high-output precision power amplifier capable of outputting up to ±200V from DC to 20kHz. Four models are available with output voltages ranging from 250VA to 2kVA, and by using boosters, it can be upgraded to 10kVA (single-phase) for every 2kVA. It is suitable not only as a power amplifier but also as a simulation power supply and AC power supply, accommodating various applications including power environment testing.

basic information
●Wide bandwidth DC～20kHz ●High output voltage ±200V ●Four modes: DC (CC/CV), AC (CC/CV)* * CC: Constant Current, CV: Constant Voltage ●Double the output voltage by connecting two units in series Connect the 4520A (2kVA) with the power booster 4521A (2kVA) to boost power up to a maximum of 10kVA ●Equipped with remote sensing terminals Compensates for voltage drop in output cables. Meets strict requirements where even slight voltage drops cannot be ignored. ●Vcc control Controls the internal DC power supply voltage (Vcc), enhances power supply efficiency, and ensures a consistently high output current.
