NuWave Introduces New Solid State Relay Mount Temperature Controller

The new SSRTC mounts directly on the input terminals of a Solid State Relay and provides a low cost, conveniently packaged temperature control solution. The input accepts J or K type thermocouples and can be used on heat or cool processes with on/off or proportional control. The setpoint can be controlled by a potentiometer or analog voltage or analog current. The temperature setpoint is proportional to the voltage or current at the setpoint input.  Status indicators indicate how close the temperature is to the setpoint.

NuWave Introduces Vernier Stepper Control

The Staging Control with Verneir – NWVS is a step controller that provides modulation in multi-stage applications such as duct heaters.  The built in 0-10V Vernier stage output allows for smooth, precision control of the load.  When the verneir output is connected to an SSR or Phase Angle Controller – SSRMAN-1P it will increase the precison of the heat control without reducing the life of the system contactors.  The unit’s LEDs show the power and output status of all of the stages including the vernier output.

New MicroTC Small Temperature Controller

Our new small temperature controller – MicroTC is our smallest and lowest cost temperature controller. The MicroTC is factory set for your setpoints and hysteresis.  A version is available with setpoint adjustment from an external potentiometer.  The small MicroTC is available in 12V and 24V versions and provides a 3 Amp MOSFET output that can be used to drive an SSR ( solid state relay) or small heater.  The integral small solid state temperature sensor eliminates the cost of an external thermocouple or RTD.

New Low Cost RC Snubber for SSRs

Introducing the new RCSB RC snubber board for Solid State Relays SSRs.

RCSB Snubber Board

The RCSB snubbersuppresses dV/dt and provide reliable commutation. This is especially important when controlling transformer coupled loads as improper commutation can result in huge inrush currents and blown fuses.  The RCSB snubber is also used on our SCR power control assemblies. The RCSB is available in 120, 240, 480 and 600VAC versions.

The RCSB Snubber Board mounts directly on the output terminals of a solid state relay. The RCSB provides overvoltage protection from transients and limits dV/dt.

New Current Limit Phase Angle Controller Module SSRMAN-1P-CL

SSRMAN-1P-CL With SSR
SSRMAN-1P-CL Phase angle control

The new SSR Mounted Phase Angle Controller Module SSRMAN-1P-CL mounts directly on the SSR input terminals and provides true linear power phase angle control of the load. The output power is based on the command input and the current feedback from the current transformer. The command can be dip switch selected from over seven different industry standard inputs. Using the SSRMAN-1P-CL with the appropriate SSR for your load will provide a modular high isolation SCR power control at a very low price.  An extensive filtering scheme and proprietary zero cross detection algorithm improves noise rejection without sacrificing accuracy.

New low cost SCR gate driver

The new ZERO CROSS SCR GATE DRIVER NWZC-SCR, is a low cost SCR driver for driving back to back SCRs in resistive load applications.  The driver board is zero cross fired and has on board MOV protection.  It provides optically isolated 5V, 24V inputs that can easily be interfaced to temperature controllers and PLC Time Proportiong (PWM) outputs.  The packaging is available in panel mountable or din rail mountable snap tracks.

NWZC-SCR SCR Driver Board

SCRs requiring 200mA of gate current or less are a good fit for use with the ZERO CROSS SCR GATE DRIVER NWZC-SCR.  Wiring of the Module is simple and requires no external power supply; the gate drive power is derived from the line supply of the SCRs.
