Import Combination Ac Transducer Bj-Qpcx — Buy in wholesale FOB from Supplier in China

The Combination AC Transducer BJ-QPCX is an electrical transducer that converts alternating current and voltage signals into a load‑independent direct‑current output proportional to active power (W), reactive power (VAR) and power factor (PF). It provides four standard DC output channels plus an optional extra channel for customised data. The unit mounts by snapping onto a DIN rail measuring 35 mm × 7.5 mm and complies with DIN‑EN 50022 and BS 5584 standards. Input specifications include a nominal current transformer rating of 1 A or 5 A and selectable AC voltage levels of 110 V, 230 V, 240 V, 400 V or 415 V with a tolerance of ±20 %.

Signal conditioning is achieved through precision instrument transformers that deliver galvanic isolation between the measurement circuit and the transducer electronics, a typical design that meets isolation voltages up to 1500 V. In the industry, similar devices are classified with an accuracy class of 0.5 % for active power and operate reliably over a frequency range of 45 - 65 Hz and temperatures from - 25 °C to +70 °C. The RS485 communication port supports standard Modbus RTU protocols, enabling integration with PLCs, data loggers and telemetry systems. These characteristics align the transducer with common power‑monitoring applications in industrial plants.

Typical users include energy‑management engineers, automation specialists and utilities that require real‑time power quality data for monitoring and control. The supplier offers the unit with a snap‑on DIN‑rail enclosure and RS485 interface, but does not publish minimum order quantities, lead‑time or exact power consumption, so buyers should request those details directly. Shipping can be arranged from the supplier’s facility in Chongqing, China, with Incoterms such as FOB Chongqing or CIF a nearby port. Confirmation of certification documents and a type‑test report is recommended before finalising the purchase.

Chongqing Blue Jay Technology Co., Ltd. is located at Jingyu Avenue No.153, Chongqing 400020, China. It is listed with a harbor trust tier, indicating a moderate level of verification on the platform. The company’s response metrics show no recent replies, suggesting a need for proactive contact before negotiations.
