40-120W 85 - 900VAC Input Voltage Power Supply PVAxx-27Bxx Series for Coal Mines Applications

 Mornsun released a new high voltage input dc dc converter PVAxx-27Bxx series which is specialized for the electrical equipment in coal mining. The new series PVAxx-27Bxx covers output powers of 40W, 70W, 120W now.

High voltage input dc dc converter PVAxx-27Bxx series has an ultra-wide and ultra-high input voltage range of 85-900 VAC, which meets the requirements of voltage fluctuations such as 127/220/380/660VAC in coal mining. The dimensions of the high voltage input dc dc converter  PVA40-27Bxx series(138*82*32mm) and PVA70-27Bxx series (155*95*41mm) are smaller than the traditional solution of industrial frequency transformer with AC/DC power supplies. Besides, they only have one input port and don't need to change the wire, which can completely avoid the risk of a wrong connection and save the cost of customers’application.

In addition, the PVAxx-27Bxx series has an isolation voltage of 4000VAC and an industrial operating temperature range of -40℃ to +70℃, and its EMS EFT/Surge is ±4KV. Protections of output short circuit, over-current, and over-voltage are included.

Current-mode PWM Controller Integrated Circuit SCM1733ASA with 75mW Standby Consumption And 650V Power MOS

图片
  Introduction of   current mode pwm controller  SCM1733ASA   In order to achieve wider application range and lower price requirements, MORNSUN launched a new current-mode PWM controller SCM1733ASA applied to small and medium-power flyback   AC/DC converter    with ultra-low standby consumption of ＜ 75mW, a maximum output power of 20W, built-in high-voltage MOS and better price-performance. It features low starting current and working currently to achieve reliable start-up and achieving low consumptions.   When the AC/DC integrated circuit (IC) is fully loaded, the PWM switching frequency is fixed; after the load is reduced, the green mode is entered, and the switching frequency will step down; during no-load and light load, it will switch the intermittent mode to reduce consumptions. Multiple control modes also can provide soft-start control that reduces MOS stress and frequency jitter control to obtain good EMI. The frequency of intermittent mode is higher than 22KHz without audio no

SOIC-16 package isolated CAN/485 transceiver (R5 Bus IC)

图片
  Based on the IC integration requirement, Mornsun switching power supply factory   launched its SOIC package isolated Bus transceiver products, also called R5 Bus IC, this May.   Advantages:   1 ） Integrated power solution with superior performance R5 bus IC integrates power supply and digital isolation in circuit design to achieve power supply isolation and signal isolation. Take TDA51SCANHC and TDA51S-41HC as examples: only 5V voltage input is requested, and up to 110 nodes of nanosecond CAN bus signal transmission can be easily achieved at 1M frequency.   2 ） High reliability design, withstand voltage up to 5000Vrms R5 bus ICs are designed according to industry standards, taking TDA51SCANHC and TDA51S-41HC as examples, the products meet the requirements of ISO11898-2 standard, meanwhile, based on the requirements of UL1577 standard, the isolation voltage is up to 5000Vrms and CMTI is up to 150kV/us. The product integrates a variety of protections such as short-circuit protection, o
