The Mean Well MDR-40-24 is a compact 40 W single-output industrial DIN-rail power supply designed for space-constrained control panels and automation systems. It accepts a universal input of 85–264 VAC (or 120–370 VDC) and delivers a regulated 24 VDC output at up to 1.7 A, with the output voltage adjustable between 24–30 V via a front potentiometer.

Key features include high efficiency (typically 88%), low no-load power consumption (<0.75 W), free-air convection cooling, LED power-on indicator, and a DC OK relay contact for remote status monitoring.

Protections cover short-circuit, overload (constant-current limiting with auto-recovery), and over-voltage. The unit measures approximately 40 × 90 × 100 mm, mounts on standard TS-35 DIN rail, operates from –20 °C to +70 °C, and carries multiple safety approvals (UL 508, UL/EN 62368-1, CE, etc.), making it suitable for industrial control, building automation, and hazardous-location applications (Class I, Div 2, T4).

NWEWDN002 (Webdyn EasyRouter)

The Webdyn EasyRouter is an industrial IoT cellular gateway and router designed for remote monitoring, data logging, and secure connectivity in demanding environments, such as building management, metering, and Industry 4.0 applications.

It features a 4G LTE Cat 1 modem (with 3G/2G fallback; regional band variants available for Europe or AU/LATAM), dual Mini-SIM slots for redundancy, GNSS (GPS, GLONASS, BeiDou, Galileo, QZSS), dual-band Wi-Fi (2.4/5 GHz), and a Gigabit Ethernet port.

Serial interfaces include RS-232 (RJ45) and RS-485 (terminal block), plus one digital input and one digital output. The device runs Webdyn’s TITAN v6 firmware, supporting Modbus RTU/TCP, MQTT(s), serial gateway modes, datalogging, VPN (IPsec/OpenVPN), SMS control, JavaScript scripting for custom applications, and multiple cloud/IoT platform integrations.

Powered from 7–30 VDC, it comes in a robust metal DIN-rail enclosure measuring roughly 113 × 30.5 × 90 mm, weighs about 195 g, and operates across an industrial temperature range of –40 °C to +85 °C.
