Answers for Global Automation Buyers

Changsha Chusoon Technology Co., Ltd. is a professional manufacturer and exporter of electrical automation components, established in 2013 in Changsha, Hunan. We run our own production lines for power electronic parts (SCR & GTO, thyristors, switching power supplies, electroplating power supplies, etc.) and combine them with certified partner factories for PLCs, VFDs, relays, sensors and meters.

What this means for you: factory-direct pricing, stable stock, traceable quality — and one accountable supplier for your whole BOM.

We supply both genuine lines and high-performance compatible replacements. Our compatible parts are engineered to match mainstream brands on dimensions, wiring, ratings and parameters — for PLCs, VFDs, contactors, relays, circuit breakers, sensors and more.

Before you order we clearly state the product type and provide datasheets and cross-reference tables, so there are no surprises. Function test reports and photos can be provided for every batch.

Very flexible. For standard catalogue items we accept sample / trial orders from just 1 piece, and we often stock 3,000+ SKUs ready for instant dispatch.

Mixed orders are welcome — combine different models in one carton. For OEM/ODM and private-label production, the minimum quantity depends on the item and is confirmed case by case.

Yes. We support private label, custom logo & colour, custom packaging and printing, parameter defaults, and even PCB-level adjustments for power modules. Full ODM from specification to finished product is available for distributors who want to build their own brand.

Send us your target specifications or a reference sample and our engineering team will confirm feasibility within 24–48 hours.

• Quality management system built to ISO 9001 standards — IQC, in-line inspection and final OQC on every batch.
• Key products carry CE and RoHS compliance.
• 100% function testing on critical power components before shipment.
• Third-party inspection (SGS, TUV, BV) and pre-shipment video inspection are both welcome.

We accept T/T (bank transfer), PayPal, credit card and Western Union.

For new customers the usual arrangement is a 30% deposit with the balance paid before shipment, or 100% PayPal for small trial orders. After a period of smooth cooperation, we are glad to discuss open account terms, L/C or D/P for regular volumes.

• Stock items: dispatch within 1–3 working days after payment.
• Production items: typically 7–15 days depending on the series.
• Express (DHL / UPS / FedEx): 3–7 working days door-to-door worldwide.
• Air freight and sea freight (FOB / CIF / DDP) available for bulk orders to 80+ countries.

A tracking number is provided as soon as your parcel is shipped.

Yes. We offer a 12–24 month warranty against quality defects (period depends on the product line). If a unit arrives damaged or fails under normal use, we replace it — no long arguments, no hidden costs.

Our export team provides 24-hour online technical support, wiring/parameter guidance, troubleshooting documents and free selection advice for the lifetime of your projects.

Absolutely. Send us the brand, model number, photo or parameters and we will cross-check across our own stock, certified factories and long-term sourcing partners. Many obsolete, rare or cross-brand equivalents that other suppliers cannot find are located within days.

Distributors can also send a full BOM list — we quote and consolidate the whole list in one shipment, saving you freight and management time.

To quote within 24 hours, the more you share the better:

• Product name and model number (or reference/brand if you only have an image).
• Required quantity.
• Destination country / port.
• Target brand, specification or a link to the original part.
