The essence of a proper and long-term operation of every device, is to use reliable components. From this point of view, relays Fujitsu are a synonym of reliability and a long lifetime.
To use a classic electromagnetic relay or rather an SSR – that´s the question, which apparently can´t be answered expressly, but pros and cons of both technologies are well known and information are easily available. We described to you features of solid-state relays for example in the article „Semiconductor better than a conductor?“. On the other hand, classic electromagnetic relays are still perspective, their features are continuously being improved and modern relays surprise by relatively small dimensions. To advantages of electromagnetic relays belong a high resistance to various power peaks, overvoltages and other disturbances. Price is also the factor saying in favor of electromagnetic relays.
Fujitsu FTR-K1 relays are power relays with a low profile, reflecting long-term experience of company Fujitsu. FTR-K1 replaced the over 20 years used VSB series relay, with which it is pin-compatible. High switching (16A) and inrush (80A) current, isolation strength up to 10kV, coil wound with a class F wire (155°C), cadmium-free contacts and RTII sealing make FTR-K1 literally a universal relay. FTR-K1 series is available in various versions – for example with up to 120A inrush current (K1-KS), with a transparent cover (K1-RG) and also with tab terminals for a simple load connection in the application (K1T).
As a standard stock in our offer can be found types FTR-K1CK005W, FTR-K1CK012W and FTR-K1CK024W with 5, 12 and 24V coils and one change-over contact (1CO, SPDT). We´re also able to supply other versions upon a request. Detailed information will provide you the Fujitsu FTR-K1 datasheet.

If we compare a power consumption of classic adapters to switch-mode ones in a no load condition (standby), we will come to surprising values. The difference can be up to tens of kWh per year.
If we take as an example a relatively common 12W 12V/1A adapter, we can suppose about 2W power consumption in a standby mode. Modern switch-mode adapters have this power consumption only 0.5W (often even below 0.3W). It is 1.5W, in other words over 13 kWh a year. If we compared an overall efficiency at a real load, we would very probably count even bigger difference, because the efficiency of a switch-mode adapter is mostly 70-90%, while the efficiency of a classic circuit (transformer + a linear stabilizer) is often below 50%.
From this point of view, switch-mode adapters Minwa , clearly win over classic adapters. They are available directly from our stock, providing all benefits of switch-mode power supplies and they are a suitable substitution for classic adapters. In the MW3 series can be found types with an adjustable output voltage in a range of 3-12V and with exchangeable output DC connectors. In the Nx series, types with a fixed output voltage can be found and with a fixed 5.2/2.1 mm output DC connector. New adapters are resistant to shortcut and overload and they meet the most recent requirements about energy efficiency (EuP/ErP 2). A relatively stable – regulated output voltage enables to directly power many devices, without any additional (LDO) stabilizers – linear regulators, what further simplifies a target device design. Thanks to small dimensions, low weight and last but not least – also thanks to a very competitive price, they represent a suitable solution of a power supply for various devices.

AKTAKOM’S AWG-4151is the latest in the series of innovative waveform generators
Miami Fl., July 27, 2012 – T&M Atlantic., distributer of the test and measurement equipment, today unveiled Aktakom AWG-4151 150 MHz single-channel digital generator.
This generator was designed using the technology of direct digital synthesis (DDS) based on 14-bit DAC and is distinguished by high functionality and specifications. The new model of AKTAKOM AWG-4151 generator has maximum oscillation frequency up to 150 MHz (for a sine wave) at the maximum frequency resolution of 1 Hz. In addition to a sine signal, AWG-4151 can generate such standard signals like square wave, pulse, noise and user signals with a frequency range from 1 µHz to 10 MHz: rising and falling exponentially, Sin (x)/x and DC signal. In addition the new AWG-4151 generator allows users create and save arbitrary shape signals into the internal memory.
AKTAKOM AWG-4151 universal generator can work not only with harmonic signals, but also has modulation opportunities and other special modes including: amplitude modulation (AM), frequency modulation (FM), phase modulation (FM), frequency-shift keying (FSK), and also operation in pulse width modulation (PWM), sweep mode, frequency and pulse bursts.
For the majority of new AKTAKOM generator models it has become traditional to use a color graphic display to display a signal waveform. The same can be seen in AKTAKOM AWG-4151 generator with color (65536 colors), 3.9 inch LCD with TFT matrix and resolution of 480×320 pixels. The use of a color graphic display simplifies users’ operation process making a generator control simple and clear. Also it helps to see a currently specified value not only in digital form but also to understand what it’s responsible for on a displayed signal form.

With the new Accucell Alpha 100 and Alpha 200 chargers you will manage it easily and moreover you don´t have to care about the type of batteries you´ll put in.
RAM batteries (rechargeable alkaline manganese) have already gained many fans, as they are environmentally friendly, have an ideal voltage of cca 1.5V and feature a very low self-discharge. They are mainly suitable for devices with a low to mid power consumption. To maintain their good properties for a long time, it is only necessary to avoid a deep discharge under 0.9V, very high discharging and charging currents and mainly to observe charging characteristics with a current limitation and a maximum voltage of 1.65V/ cell.
New microprocessor controlled chargers Alpha 100 and Alpha 200 control every channel separately, that´s why it is possible to charge any number of batteries from 1 to 4 pcs. They are designed to observe an optimum course of charging for RAM accumulators. This is also reflected in the charging current of 155-195mA x4 (AA) and 70-100mA x4 (AAA) respectively. Charging of common RAM cells lasts approx. 2-12 hours, depending on their capacity and a level of discharge.
New chargers provide one extra bonus – they are also able to charge NiMH and NiCd cells, because they are able to recognize the type (chemistry) of an inserted battery (from a voltage curve at charging), adapting a charging course accordingly.

Schurter 5500.0655.1 line filter will enable it to you and provides an universal usage, independent on the type of the of the inlet power socket used in your device.
It is necessary to use an input line filter in almost every device. At its choosing, you have a possibility to use a filter combined with an input line socket , or a standalone, most often designed for PCB mounting.
Thanks to a big amount of various electric devices with a non-linear power consumption, the line voltage sinusoid is far distant from a clean form found in books of mathematics. Despite still more stringent EMI and EMC regulations, it is necessary to use line filters – also thanks to the fact, that modern digital circuits with a very low power consumption are potentially more sensitive for disturbances. A similar situation is at analog circuits, where more sensitive circuits are used (amplifiers, AD and DA converters, …). A usage of a filter brings two benefits – a better protection of a device from disturbances and also prevents a noise leakage from your device to a mains line.
A novelty in our portfolio is the Schurter 5500.0655.1. line filter for PCB mounting. Advantage of the PCB version is, that it doesn´t require a space on your device´s rear panel. With a maximum current of 6A, it is suitable even for relatively powerful devices. In the Schurter 5500.0xxx datasheet can be found detailed graphs about the filter attenuation in a common, as well as differential mode. For highest demands regarding EMC, it is possible to equip the filter with a metal shield.
