Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Transformers And Substation Equipment. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The EW-90KW is a three-phase-to-single-phase variable frequency power supply. It is described as converting three-phase AC input, with 380 V at 50 or 60 Hz given as an example, into a single-phase supply with adjustable output voltage and frequency.
Example output voltage settings include 220 V, 110 V, and 100 V, while the stated adjustable frequency range is 40–70 Hz. Operation is managed through a touch LCD interface designed for direct parameter setting.
The equipment includes voltage-gradient and transient functions for configuring voltage changes and change times. It also provides measurement of voltage, current, active power, and apparent power. A synchronous reference signal is available when voltage and frequency change.
For integration into a controlled power or test environment, the unit supports RS-232 and RS-485 communication using the Modbus protocol for remote control and ection. The stated working-environment temperature range is 0–40°C.
The source describes output-port voltage fluctuation as remaining within 1 V when the load changes from 0% to 100%. Buyers should confirm the test conditions, measurement method, applicable output-voltage setting, and load type behind this figure before using it as an acceptance criterion.
Customization is available, including customized voltage.
Before procurement, confirm the required three-phase input voltage and frequency, single-phase output range, continuous power rating, load characteristics, communication configuration, enclosure and outdoor-use requirements, mobility features, and the exact equipment included in the proposed system.
The product is listed with CCC certification, but buyers should request the certificate scope and verify that it covers the ordered configuration.
Packaging is described as export-standard packaging;shipping method, delivery schedule, warranty, installation scope, and after-sales terms should be established in the purchase contract.
