A new range of Solid State Relay modules with 30 A AC switching capability is now available. Housed in a plastic casing with integral aluminum heat sink and of 22.5 mm width, these SSRs feature high thermal efficiency (guaranteeing full load operation without de-rating over an ambient temperature range of -20 to 40 ° C)

Available In Two Different Terminal Versions:
• “Relay” version, i.e. where input and output terminals are on opposite sides - more suited for new installations, where it is easier to achieve greater separation between input and output wiring.
• “Contactor” version i.e. where input and output terminals are adjacent to one another - useful as a replacemenfor other SSR or electromechanical contactors in existing applications.

There Are Also Two Options of Input Voltage:
• Rated input voltage 24 V DC input (range 4 ... 32 V DC)
• Rated input 230 V AC (range 40 ... 280 V AC)

There Are Two Options of Type of Output Switching - Both Rated at 30 A , 400 V AC (range 40 ... 480 V AC):

Schurter is expanding the successful UMT-H series of SMD fuses with 13 additional rated currents. The expanded series – which covers rated currents between 160 mA and 10 A – will now protect an even broader range of applications. With a rated breaking capacity of 1500 A, this compact SMD fuse is capable of protecting against short circuits, while providing reliable overcurrent protection.

Schurter now offers the UMT-H in a total of 19 rated currents between 160 mA and 10 A at voltages up to 277 VAC and 250 VDC. The compact SMD fuse stands out with its high breaking capacity of 1500 A at rated voltage. This key feature, among others, makes the square UMT-H a space saving alternative to classic cylindrically shaped cartridge fuses (e.g. 5x20 mm).

Besides a wide range of applications in power circuits and sensors, the UMT-H is particularly well suited for the primary protection of power supply units rated up to 277 VAC. It is also suitable for use in the protection of single phase industrial appliances. The high breaking capacity of 1500 A, the spacing between the end caps of >10 mm and the ability to be potted also make these devices useful in applications according to IEC 60079-11 that involve explosion protection. Examples include first responder equipment, industrial controls exposed to oil and gas environments, and lighting ballasts.

Features and benefits:
- High rated voltages up to 277 VAC / 250 VDC
- High breaking capacity (H) of 1500 A at rated voltage
- Initially six rated currents from 160 mA to 2 A (others will follow)
- Time-lag (T) characteristics according to UL 248-14
- Compact, square design
- No rolling away during PCB assembly and soldering
- Safe interruption at line voltage
- Halogen-free and RoHS-compliant

Applications:
- Primary protection on SMD PCBs
- Industrial electronics
- Sensors
- Power supplies
- Explosion protection (IEC 60079-11)
- Lighting

Finder's new thermostat, the type 1C.61, with adjustment sliders designed to respond to the need for practicality, simplicity and comfort in the control of room temperature.

Uniquely innovative, the 1C.61 is the first “touch slide” capable of combining the simplicity of a touch screen display with exclusive “guided programming”, with the ease of adjustment of the 24 linear sliders for temperature setting.

The size and design make it unique at only 17mm thick and it is finished in an attractive white cream and grey. The cover, with spring assisted opening and closing, offers protection to the sliders from dust and gives continuity to the aesthetic curves.

The backlit display features large font size and “Dynamic” icons, offering excellent legibility. However, despite the large display and backlight, the advanced electronics of the new 1C.61 cleverly limits the power consumption, extending battery life up to 2 years.

Simple but fully featured: The 1C.61 fully justifies this slogan, since by entering the “setup” an extensive range of advanced features and functionality can be programmed.
For example, you can set the time of day to the nearest 15 minutes; the “day” function allows you to program any 1 of 3 modes (Off, Manual, Sliders) for each day of the week.
It is possible to make the display show the temperature of an (optional) external sensor, or even make it the main controlling sensor.


Innovative functions can be “set” to fully block changes to the thermostat (under PIN control), protecting all parameters entered including the settings of the sliders. Alternatively, a simple lock against the effect of accidental or malicious touching of the display buttons can be selected. The possibility of calibration to align the display to the perceived temperature is also an option.
A remote contact can be employed to alter the operation of the thermostat by forcing the output switch off manually or allowing it to follow the normal program. In case of difficulty the Reset function will restore all the factory settings, returning the product to “as purchased” state.
Finally, the manual timer (or vacation) setting has been simplified by adopting the concept of a “calendar”, whereby setting the time and date of the return from holiday ensures the thermostat will automatically return to the conditions of automatic programmed temperature control.
