Introduction of   AC/DC Converter LD-R2 Series Due to the development of IoT (Internet of Things) and the 'smart home' concept, the requirement of household appliances on the safety and dimensions are more important than ever. MORNSUN ultra-compact   AC/DC converter LD-R2 series, for example, 1 x 1x 0.7 inches of LD03/LD05 series, is the ideal power supply for applications with space limitation.   With the universal input voltage of 85-305VAC, an operating temperature range of -40~85℃, and an efficiency of 87%, the   ac to dc converter   LD-R2 series can be used for applications in commercial and industrial. The 2-Y-capacitors design, EMI class B without external components requirement, and No-load power consumption as low as 0.1W make them the perfect match for the household appliance.   The LDxx-23BxxR2 series is provided with the IEC / EN / UL62368 and the IEC / EN60335 and the IEC / EN61558 safety standard for domestic applications. These compact modules are very suitable

  100-1000VDC Input DC /DC Converter——PV15-27BxxR3 series   Introduction of   PV15-27BxxR3 series   1000v dc dc converter  PV series has received a solid reputation for its powerful performance and cost-effective since its launch. With an optional input voltage range of 100-1500VDC and an operating temperature range of -40~70℃, PV series can be used for applications of photovoltaic combiner boxes, inverters, energy storage BMS and charging piles, etc. These modules feature an isolation voltage of 4000VAC, output over-voltage protection, short circuit protection, and input against reverse protection which ensure the stability of the circuit.   Along with our technological advancements, we upgraded and launched our new generation product PV-R3 series with better performance and better cost. The newest PV15-27BxxR3 series has an input range of 100-1000VDC which could withstand a transient voltage up to 1200VDC for the 60S. And they are designed to have the input under-voltage protection ，

  The flyback converter in the dc dc switching power supply  is the most common AC/DC power supply. With the development of integrated circuit technology, most of the circuits in the flyback converter are integrated into the IC, and there are few peripheral components. That makes it possible to build a power supply that has general functions with just adding a suitable transformer. It’s simple but not optimized for personalized and differentiated needs, engineers are always puzzled to balance the design cycle, cost, reliability, ease of use, dimensions, performance, and personalization of power supply. And now, MORNSUN's newest   diy ac to dc converter   "LS-R3" series can resolve this puzzlement.     Save Cost from Multi-dimension The cost of the power supply section accounts for a large proportion of the cost of electronic devices, forcing many customers to use discrete solutions to reduce costs. But discrete solutions can only reduce raw material cost, there’re still m

  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

  Introduction of   RS485 P ower   Transceiver—SCM3403ASA   SCM3401 and SCM3402 family, our Half-duplex RS-485 transceiver with 3.3V or 5V powered, received a warm response from the market since its launch. To better fulfill a wide power range and more competitive cost, SCM3403ASA complying with   TIA/EIA-485 is launched to be compatible with 3.3V and 5V powered.   The SCM3403ASA is half-duplex and low-power isolated rs485 transceiver with power , which the ESD protection of bus port above 15kV HBM and bus withstand voltage up to ±15V. It   includes a driver and a receiver, both of which can be independently enabled and disabled. When both are disabled, they are a high-impedance output state.
