DC Input AC Load 3 Phase Solid State Relays

● Three phase solid state relay● 5-32Vdc input● 24~480Vac load● only available with 10/25/40 amps● Zero-crossing trigger● For resistive load only

● Three phase solid state relay● 90~280Vac Input● 24~480Vac load● From 10 amps up to 200 amps● Zero-crossing trigger

The JX-1DA48 (black flip-cover housing) and KT-1DA48 (grey housing) are single-phase, DC-controlled AC solid state relays designed as direct-fit, cost-effective alternatives to Omron G3NA-style SSRs. Both variants share identical electrical specifications and the same compact physical footprint, differing only in housing style and colour. Accepting a DC control voltage of 3.2–32 VDC, these relays are directly compatible with PLC transistor outputs, microcontroller I/O, and standard industrial DC control signals. The AC load side supports 24–480 VAC at 50/60 Hz, covering 110 V, 220 V, 380 V, and 480 V systems worldwide. Load current ratings of 10 A, 25 A, and 40 A are available, with all three ratings sharing the same physical dimensions for easy interchangeability. Zero-crossing trigger technology ensures switching occurs at the natural zero-crossing point of the AC waveform, minimising EMI and extending load service life. A built-in RC snubber circuit is incorporated across all three current ratings, providing additional protection against voltage transients without requiring external components. The 10 A, 25 A, and 40 A models all use a TRIAC output stage, offering reliable bidirectional switching. An LED status indicator provides instant visual confirmation of relay activation. The panel-mount housing includes a protective cover (JX-1DA48) for added terminal protection. Private label and custom logo laser printing are available on request.

This is a single phase SCR power regulators and temperature controllers 2 in 1 units, in a typical heating system, you would need a temperature controller and a SCR power regulators, and they are two separate devices, we go further and build this two devices in one package, this saves a lot of efforts for panel builders when it comes down to wiring, and RS-485 modbus is a standard feature, controller can be integrated to systems with HMI or PLC etc. the load can be directed wired to this thyristor power regulators, and it works with all kinds of inputs, Thermocuple, RTD, analog signal

SCR-51 series is a compact design cost effective three phase SCR power regulator, works perfectly for resistive load. With built-in heatsink and cooling fans.  Makes it very easy to use. Load option starts from 40 amps all the way up to 100 amps,  with a built-in overheat thermo protection to make your system always protected. Clear digital display for temperature and input/output indication.

Maxwell DR04D is a din rail mount PID temperature controller, 4 channel configuraitons, support thermocouple inputs(K,E,J,N,W,S,T,R,B), and output can be Relay, SSR Drive, or analog like 4-20mA, 0-10VDC, PID or ON/OFF control mode, RS-485 modbus communication as standard features, 24VDC source for greater saftey, auto/manual control switchable, when you have a sensor failure, the system can be quickly switched to manual control mode to maintain the temperature, soft-start and run/stop features.

The Maxwell SCR-7 Series is an advanced, three-phase intelligent digital power regulator designed for precise and reliable control of resistive heating loads in industrial applications. Engineered with a fully integrated design, it combines the SCR module, high-efficiency heatsink, and cooling fans into a single, compact unit. The SCR-7 series features a comprehensive digital display for real-time monitoring of output ratio, temperature alarms, and phase status. With support for multiple analog input signals (including 4-20mA, 0-10VDC, and 0-5VDC) and optional RS-485 Modbus RTU communication, it seamlessly integrates into modern PLC and automated control systems. Built-in protective features such as soft start, auto phase detection, and over-temperature alarms ensure maximum safety and longevity for both the regulator and the connected load.
