AI-Powered supplier vetting

SummarySHENZHEN SCIEO ELECTRONICS CO., LTD. is a Shenzhen-based limited trading company offering electronic instrumentation equipment. It has 15 employees, provides ODM and OEM services, and supports multiple forms of customization, but does not provide 3D software design or SDKs and reported no new products in the past year. The supplier has in-stock capability and stated peak- and off-season lead times of one month, with service quotations accepted under FOB, CIF, CFR, and EXW terms. It lacks overseas warehouse and showroom capabilities. Audit information identifies CTI as the auditing organization, with a report period from April 19, 2025 to April 18, 2026, but the audit result is recorded as 0 without an explanatory assessment. Evidence is insufficient to confirm certification, financial strength, after-sales effectiveness, production capacity, or customer cases.

Supplier typeThe supplier is identified as a limited company and trading company located in Longhua District, Shenzhen, offering electronic instrumentation equipment. It is not part of a larger company group and has 15 employees, indicating a relatively small independent trading operation.

R&D capabilityThe supplier has two R&D engineers and provides ODM services, but it launched no new products in the past year. It does not provide 3D software design services or an SDK, which limits the evidenced scope of its innovation and technical-development capabilities.

Customization capabilityThe supplier explicitly supports flexible, minor, and full customization, as well as customization from designs and samples, and also provides ODM and OEM services for popular brands. This is direct evidence of broad customization support, although it does not include 3D software design or SDK capability.

Client casesThe supplier reports that 50%–80% of buyers are repeat buyers and states that it provides OEM services for popular brands. These records support some evidence of customer retention and brand-related service experience, but no customer names or independently verifiable case details are provided.

Product Q&A

Q:How can the N38300 series achieve up to 1.8MW of total output power?

The N38300 incorporates a sophisticated master/slave parallel function. By connecting multiple identical units via standard interfaces, the system automatically balances current sharing among modules, allowing you to scale total power from a single unit up to 1.8MW seamlessly.

Q:What is the CC/CV Priority function, and why is it important?

This function lets you select either the voltage loop or current loop as the primary feedback control. Choose CV priority for voltage-sensitive devices to avoid overshoot, or CC priority for low-impedance loads like battery charging. This smart feature effectively prevents surge damage to your device under test (DUT).

Q:What communication protocols are supported for integration into automated production lines?

The N38300 comes standard with LAN and RS232. To accommodate diverse ATE architectures, optional interfaces including GPIB, CAN, RS485, and USB are also available, ensuring flexible and hassle-free system integration.

Q:Can this power supply simulate battery or fuel cell internal resistance?

Yes. The N38300 features a built-in internal resistance simulation function. You can easily set the resistance value via the front panel or host software. The power supply will dynamically adjust the output voltage based on output current (U = U_set - I * R_sim), accurately mimicking the voltage droop characteristics of real batteries under load.

Q:What protection features are included to ensure system and DUT safety?

The N38300 is equipped with comprehensive hardware and software protections, including Over-Voltage Protection (OVP) , Over-Current Protection (OCP) , Over-Power Protection (OPP) , Over-Temperature Protection (OTP) , and Under-Voltage Protection (LVP) , providing a multi-layered safety net for both the equipment and your valuable test articles.
