With a host of design features to improve both reliability and efficiency, the 78 Series of switched mode power supplies from Finder gives control system builders a stable and dependable low voltage DC supply. 91% efficient, and drawing only 0.4W in standby, this series of modular, rail mounted DC power supplies comprises 24VDC, 36W; 24VDC 60W and 12VDC, 50W output variants that support universal AC or DC supply ranges, respectively 100-265VAC and 140-370VDC.
Integrating the latest protection technologies, the 78 Series includes: thermal protection with fast output voltage shutdown; short circuit protection with ‘hiccup’ (auto-recovery) mode and overvoltage (varistor) protection. In addition, the power supplies’ high inrush current handling capability means they will safely tolerate loads with high current transient characteristics, such as capacitive circuits and solenoids fitted with ‘economy’ resistors.
To help minimise downtime in the event of a fault, the power supply inputs are protected by an easy access internal fuse, with an adjacent spare fuse ensuring an even more immediate fix. Able to be interconnected in either dual (bi-polar) or series configuration, multiple 78 Series power supply outputs can also be ORed using standard diodes to support both manual and automatic redundancy schemes, further augmenting control system reliability.
Measuring only 70mm wide and 60mm deep, these highly compact 35mm rail mounted power supplies can also help to reduce control panel size. Qualified to EN60950-1 and EN61204-3 normes, they are fully compliant with global EMC standards for power supply design.

Finder has announced the introduction of a pair of panel thermostats designed to maintain constant temperature levels in control panels and enclosures. Suiting the needs of both simple and sophisticated heating and ventilation systems, the 7T Series thermostats help to improve component reliability and preserve instrumentation accuracy through enhanced temperature setting and control.
With red or blue temperature setting dials to clearly identify the heating and ventilation variants, the 7T thermostats are IP20 rated and come in slim 17.5mm rail mounting housings, ensuring easy installation and usage in compact panel designs.
A temperature setting range of between 0 and 60ºC makes them suitable for a wide range of environments, while their snap action bi-metallic sensor means a positive switching action and a long electrical life (100,000 cycles). The thermostats’ output contact (normally closed for heating control, normally open for ventilation control) is rated at 250VAC, 10A, enabling them to directly switch heater or fan loads up to 2500VA AC1 and 250VA AC15.

Finder has announced the introduction of a range of eight modular, 22.5mm wide rail-mounted timers designed to provide a complete range of timing functions, while keeping part number holdings to the absolute minimum. The multi-voltage 83 Series of multi-function and mono-function timers handles 14 different timing functions, with time scales between 0.05 seconds to 10 days and offers either single or double pole variants.
To maximise flexibility the timers support a very wide working voltage range, from 24V through to 240V AC or DC, making them suitable for mains or low voltage AC operation as well as DC battery supplies. With changeover contacts rated for 16A, the 83 Series is capable of switching AC1 loads of up to 4KVA or single phase motors up to 0.5kW. For easy maintenance, both flat blade and cross head screw drivers can be used to adjust the range and function selectors, the timing trimmer and to disengage the rail mounting clip.
The single pole 83.01 and double pole 83.02 multi-function timer variants both offer up to 8 different timing functions, including a special watchdog function allowing users to monitor repeating processes by resetting the time period each time a “watchdog” pulse is received, with the continuous presence or absence of a pulse beyond the set time triggering the release of the output contacts.
The 83.02 timer also provides the facility of external potentiometer time setting, enabling the timer to be adjusted from the front of control panel or enclosure, whilst assuring the security of timer function and time scale settings. In addition, to further maximise flexibility and minimise part number stocking, it also offers users the option to select between either 2 timed or 1 timed and 1 instantaneous contact.
The third multi-function timer in the series, the 83.91 provides 4 asymmetrical flasher timing functions: starting pulse on; starting pulse off; as well as starting pulse on and starting pulse off both with a control signal input allowing timing to be initiated from a remote sensor operating at a voltage other than the supply voltage.
Completing the 83 Series timer range are 3 single pole mono-function timers: the 83.11 for on-delay; the 83.21 for interval; 83.41 for off-delay with control signal; and a pair of 2 pole mono-function timers: the 83.62 for power-off delay (true off-delay) and the 83.82 for star-delta timing function.
