PRODUCT SHOWCASE Global power supply repair Switchmode specialises in the repair of all power supply equipment, including those where technical information, support, spare parts and/or test fixtures are scarce or unavailable. Since 1984, Switchmode has serviced over 6000 models of equipment from more than 1400 different manufacturers. We have undertaken power supply repair for many standard power supplies as well as more unusual units. Switchmode’s engineers and technicians are supported by a technical database from which they can readily access computer records (held for more than twenty years) of every electronic component removed, tested and replaced in the power supplies repaired. For professional service, send your power supply repairs to Switchmode. Examples of power supply equipment that we regularly repair includes converters, amplifiers, rectifiers, UPSes, switch-mode power supplies, DC regulated power supplies and AC power supplies from medical lasers and radio broadcasting to ship’s anchors and radar systems. Switchmode is based in Hornsby, Sydney, serving all of Australia and beyond. Contact us to discuss how we can help you with your power supply repair requirements.

These generic 802.11 b/g/n WiFi microcontroller modules provide engineers with high-performance, single-core SoCs in both PCB and IPEX antenna configurations. They are an ideal choice for IoT, wearable electronics and smart home applications. The Espressif ESP32-S2 MINI modules offer secure and cost-effective communication, incorporating an Espressif ESP32-S2FH4 SoC with a 240MHz LX7 CPU. They have 4MB of external SPI flash and cryptographic accelerators to enhance security performance and protection. The ESP32-S2 MINI modules also include a low-power co-processor for monitoring SPI, I2S, UART, I2C, the camera interface, as well as the modules’ 43 GPIO pins. Both modules operate from -40 to +125°C, making them ideal for a wide range of industrial, consumer and lighting environments. Mouser also offers development tools for the ESP32-S2 MINI modules, including the Espressif ESP32S2-MINI-1 development kits and the DFRobot ESP32-S2-DevKitM-1 development board.

This family is unity-gain stable and has a typical gain-bandwidth product of 1MHz or 3MHz. The benefits of these low-cost devices include: • Operation from a single supply as low as 1.8V • A low maximum offset voltage of only 1.6mV and low noise, enabling excellent measurement accuracy without breaking the budget 52 Silicon Chip • Both the MCP6006/7/9 and MCP6476/7/9 series of amplifiers consume as little as 90µW (1MHz GBW [gain bandwidth]) and 252µW (3MHz GBW) per channel, respectively • With a start-up time of only 6µs, these devices can be switched on and off, so they only draw power when they are needed • They are ideal for harsh, electrically noisy environments • Integrated EMI filters provide additional rejection of high-­frequency interference • They are specified over the Australia's electronics magazine extended temperature range from -40°C to +125°C.
