Homemade tablet CarPC
The momentary hold relay board and the accessory delay module are components designed for automotive applications. The momentary hold relay board powers the GPS unit and the tablet, eliminating the need for manual button activation. The accessory delay module is...
Adjustable High voltage power supply
The schematic diagram is derived from the circuit for an Adjustable High Voltage Power Supply, which can output voltages ranging from 0 to 1000V. A suitable source of alternating voltage for the high voltage converter is 12V / 800mA. The...
Low Cost High Voltage Power Supply
This high voltage, low current power supply has been designed for various experiments in systems and synthetic biology. The schematic and board layout are provided below. The circuit can output up to +1,866 VDC at under 1 mA and can...
High Voltage Power Supply for Valve Preamplifiers
The amplifier feeding the final amplification stage operates with unstabilized voltage. The output stage, utilizing push-pull operation, exhibits significant rejection of the supply voltage. However, the earlier stages do not provide the same level of rejection, resulting in unwanted noise....
8 Channel LPT Relay Circuit
This circuit utilizes a Power Battery Terminal (PBT) to facilitate simple relay output and auxiliary power connections. An LED on each channel serves to indicate the status of the relay. Berg pins are provided for connecting power and trigger voltage....
DC relay delayed release circuit 2 b
The circuit depicted in Figure 6-24 includes a relay coil with both ends connected in parallel to a resistor (Rf) or an auxiliary diode (VD). This configuration is intended to enhance power after a short circuit occurs in the coil...
High Voltage Generation For Xenon Tube Applications
Power demand in portable designs can require, in specific applications, more than 1 A. A method involves paralleling two DC to DC converters on the same load instead of using a single higher current converter with a lower switching frequency....
Relay protection circuit
Operating power protection devices can be categorized into two types: DC power supply operation and AC operation. AC operating power is favored due to its lower investment costs, simpler operation, and reliable secondary circuit maintenance, making it widely used in...
