Key features

Supports up to 1200A sinking current with a minimum operating voltage as low as 0.2V.

making it an ideal solution for fuel cell stack and single-cell testing where low voltage and high current are critical.

Offers independently adjustable rise and fall slew rates,

allowing users to customize current transition speeds based on DUT characteristics to simulate real-world load variations and prevent inrush damage to the device under test.

Built-in Programmable Sequence Test (SEQ) function supports up to 100 sequence files with 50 steps each,

enabling automated execution of complex dynamic load profiles to significantly improve testing efficiency.

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:Can this electronic load be used to test a single fuel cell stack piece?

Yes. The N62400 series can sink 1200A at as low as 0.2V, making it highly suitable for testing single fuel cell sheets (typically below 1V) under high-current conditions.

Q:What's the difference between hardware CR mode and software CR mode?

Hardware CR mode is implemented via dedicated analog circuits, offering faster response and better stability without oscillation during rapid voltage changes. It is particularly advantageous for fuel cell testing where internal resistance varies dynamically.

Q:How do you perform overcurrent protection (OCP) testing with this device?

The built-in OCP test function allows users to set start current, step current, and stop current. The load will automatically sweep and capture the protection trip point without manual programming.

Q:Which remote control methods does this load support? Does it support CAN bus?

It supports LAN, RS232, and CAN communication interfaces. The CAN interface enables direct integration with commonly used bus systems in automotive and industrial applications.

Q:What is the purpose of the ESR test function?

The optional built-in ESR (Equivalent Series Resistance) test function allows quick measurement of battery or fuel cell internal resistance, helping users assess cell health without purchasing a separate dedicated resistance meter.
