The RCT2000D Series isolated DC-DC converters are the ultimate
solution for flexible power needs. Capable of sourcing from
batteries or varied DC inputs, they generate precisely regulated
24/48/110/220VDC outputs with exceptional consistency. Their
adaptive design excels in voltage regulation, noise suppression,
and efficiency, while rugged construction ensures reliability
during 24/7 operation and in high-temperature environments. With
compatibility across a wide input range (24/48/110/220VDC nominal)
and support for positive/negative grounding, these rackmount
converters offer plug-and-play versatility for industrial
automation, telecommunications, and off-grid systems, delivering
clean power wherever it’s needed.

Solutions
For telecommunications companies operating in China and
internationally, we present a holistic solutions package. Starting
with an in-depth site survey, we gain a thorough understanding of
the existing infrastructure and challenges. Based on this, we
propose professional plans that are not only innovative but also
highly practical, meeting the customer's specific needs.
Our technical support is second to none, offering prompt and
effective solutions to any issues that may arise. Regular
maintenance services further guarantee the longevity and
reliability of the systems. With a well-coordinated team and a
wide-reaching network of partners, we ensure a seamless and
efficient service delivery process from start to finish.
FAQ :
For standard products in stock, we guarantee 2 - 5 working days from order confirmation to dispatch. Customized solutions (e.g.,
products with special specifications or branding) usually take 10 - 15 working days, depending on the complexity. Last month, a telecom client needed
200 units of voltage - stabilized equipment with customized
housing, and we delivered ahead of schedule within 12 days.
Yes, we ship globally via DHL, FedEx, or sea freight (LCL/FCL). For
customs clearance:
- We provide commercial invoices, packing lists, and certificates of origin to facilitate smooth customs procedures;
- For repeat customers, we can pre - register your tax ID with
logistics partners to minimize delays (e.g., EU clients with EORI
numbers).
Our technical team offers end - to - end integration support:
▸ Pre - sales: Free compatibility consulting (e.g., whether our
power modules fit your existing system architecture);
▸ Post - sales: 24/7 remote assistance via video call or TeamViewer
(we recently helped an Indian client troubleshoot a wiring issue
within 3 hours);
▸ On - site support: Available for large projects (travel costs
covered by clients, but waived for orders over $50,000).
All products meet:
- ISO 9001:2015 for quality management;
- Regional safety standards (e.g., CE for Europe, UL for the US, CCC
for China);
- Industry - specific certifications (e.g., IEC 61000 for EMC
compliance in industrial applications).
Certification documents can be provided upon request—we even helped
a medical device client fast - track their product approval by
supplying relevant test reports.
