AC-DC POWER SUPPLIES RADIO

AC-DC POWER SUPPLIES RADIO

AD Series Desktop Desktop Power Supplies The Desktop Power Supplies, popularly called the ?Wedge? due to its distinctive ergonomically friendly shape, offer a convenient way to convert 12Vdc mobile radio transceivers for use as desktop base stations. They will operate from AC supplies, either 115V or 230V without manual adjustment. The continuous rating is 108W (9A), sufficient for most radio transceivers on the market. We started making these for Motorola radios 5 years ago, now we have 18 varieties for 8 manufacturers. Integrated Battery Back Up Facility The product has a built in battery back up facility which will allow the supply to continuously trickle charge a battery which will automatically power the transceiver in the event of a mains supply cut. Designed for Ease of Use The wedge gets its name from its unique shape which is designed to angle the radio towards the user for ease of operation. A microphone clip is supplied for each side of the radio (except universal units) for either left or right handed operators. A red LED indicates when the output from the unit is supplied from the mains. If a battery back up has been fitted, and the mains supply should fail, a yellow LED will light, indicating that the output is supplied from the back up battery providing the operator with reassurance of the status of the equipment. The ever popular ?T? shaped bracket allows the power supply to be fitted quickly and simply making for a fast and neat installation. Radio Transceiver + Alfatronix Desktop Power Supply + Alfatronix Battery Back Up Box = Fully Integrated Solution Can?t find what you?re looking for? Alfatronix Desktop ?wedge? power supplies are configured to suit a wide range of radio transceivers from many manufacturers ? see list overleaf. However, if you use a variety of radio types or cannot find a compatible unit, try our UNIVERSAL unit, P/N AD UN UNI. This uses a mechanical interlocking fixing system (3M ?Dual Lock?) to fix the transceiver securely to the power supply. AD Series power supplies can also be fitted with DIN rail clips for rack mounted applications The desktop units are supplied with endplates configured to fit with your radio. For a complete system, order our fully compatible battery back up box ? P/N AD BBB (to include a 7Ah battery) or AD BBB NB (excluding the battery). >>>

POWER MANAGEMENT - LINEAR REGULATOR MPC18730

POWER MANAGEMENT - LINEAR REGULATOR MPC18730

The MPC18730 Power Management device regulates five independent output voltages from either a single cell Li-Ion (2.7 V to 4.2 V input range) or from a single cell Ni-MH or dry cell (0.9 V to 2.2 V input range). The MPC18730 includes 2 DC-DC converters and 3 low drop out (LDO) linear regulators. The output voltage for each of the 5 outputs is set independently through a 3-wire serial interface. The serial interface also configures the versatile start-up control system of the MPC18730, which includes multiple wakeup, sleep, standby, and reset modes to minimize power consumption for portable equipment. In single cell Li-Ion applications two DC-DC converters are configured as buck (step-down) regulators. In single cell Ni-MH or dry cell applications, one DC-DC converter is configured as a boost (step-up) regulator, and the other as buck-boost regulator. The DC-DC converters’ output voltages have set ranges 1.613 V to 3.2 V at up to 120 mA, and 0.805 V to 1.5 V up to 100 mA through the serial interface. >>>

THERMOTRONIC LC1 ELECTRONIC TEMPERATURE SWITCH SENSOR

THERMOTRONIC LC1 ELECTRONIC TEMPERATURE SWITCH SENSOR

Thermotronic LC1 Electronic temperature switch sensor Thermotronic LC1 Electronic temperature switch sensor for Hydraulic and Lubrication Oil applications To find out prices for this product please call us or use our online enquiry system. If you send an online enquiry the Application Description is important to us in order to identify the best solution available - so please give us as much technical information as you can. Don't forget to enter your quantity, then just click on add to my enquiries. DetailsSince the viscosity of oil changes with the temperature the oil temperature must be controlled. Depending on the application the need to control the temperature can range from keeping minimum or maximum levels, triggering alarm points or emergency shut off. The Thermotronic LC1 has been developed for such applications where both the output as well as the hysteresis must be very precise. Appllications with settings close to ambient temperature are typical. The signal is generated by an DTD (PT 100) and is converted by an electronic circuit into an adjustable output. The hysteresis is fixed to 5 K but can be adjusted to 10 K if required. For maintenance the electronics and the sensor can be removed from the housing without the need to remove the unit from the power pack. This avoids the need to drain the power pack/reservoir. Technical featuresrugged design electronics removable for inspection optional DIN or M12 connector cable direction adjustable for DIN connector in 90 ° steps elastomer seal alarm points and hysteresis adjustable output with adjustable relays to NC or NO 4-20mAanalogue out put >>>
