DC-DC converter

DIN rail mount DC-DC Converters

Current Logic now introduce a new series of DIN rail DC-DC Converter. They can quickly snap onto a DIN rail with built-in DIN rail clips that require no additional brackets.

First made converter in din rail mountable enclosure is a 24V to 12V converter with rated power at 100W (120W max). It is for industrial use and is more tightly regulated than former 24V to 12V converter. The module also has an adjustable output from 11~13V. This give user more convenience in designing their own system.

48V to 24V converter

Current Logic now has a new converter add to non-isolated dc-dc converter family.

48v to 24v converter. This dc-dc converter step down a input of 42-56VDC to 24V output. Like other non-isolated converters from current logic, this switching mode converter have 90%+ effeciency and waterproof casing. Robust and clean design of this module help users to easily plug into their applications.

Water-cooled DC-DC Power Converter for EV/HEV

Last year we were asked several times whether we have a water-cooled high power dc-dc solution. Current Logic have been providing air-cooled and fan-cooled dc-dc power supply for years, but didn't have water-cooled units.

After some research, we find many EV/HEV projects have a water-cooled solution for power supply. And we decided to explore the ideas. With help of local institute and talented engineers from partner companies, we came to a dc-dc power solution that is for EV/HEV indeed.

High Power DC-DC Converters, Isolated and waterproof

Current Logic has much experience in making High Power DC-DC Converters

These converters ranges from 500W to 2000W, they were mostly used in mining and energy industry. Recently, as EV and hybrid powered vehicles drawing more and more attention, they begin to appear in vehicles.

12V to 24V Step-up DC-DC Converter, 72W to 360W

Current-logic.com set up online shop at the beginning of this year, and it seemed working well. More and more products will become 'online' in coming days.

Some typical types available now:

12V to 24V step up converter, 360W max
12v to 48V step up, 150W max
24v to 12v step down converter, 720W max
12/24V to 5V step down, 100W max
36V to 12V step down, 180W max
48V to 12V step down, 120W max

Adjustable Constant Current DC-DC Converter For Solar LED Applications

The current adjustable DC-DC converterin my last post has come out this month. It takes more time to develop than we expected.

The most charming feature of this module is that users can control the output current with potentiometer on board. Current can be set at any number between 750mA ~ 3A, power 2W ~ 100W. This means that user will have most elastic options in different power/current level designs.

Constant Current DC-DC Converter

The -40~80 degree working temperature DC-DC converter I mentioned last time(12v to 24v, 500W), results in a piece of 220*165*75mm, 4.5 kg rock. Water-proof, shock resistant and other protection like short-circuit, lack input voltage etc.

The client couldn't agree to compromise on the temperature, and the unit price finally come to about $260 for 100 pcs quantity.

I'd like to post the picture of the device, however, it may bother the buyer since it was an OEM product. And it doesn't look very nice. Looking is not that important, right?

Step Up, Boost DC-DC Converter for Car

dc-dc converter for car

Days ago I received an enquiry asking for a step up dc-dc converter, converting 12v to 24v with 25A output. That is up to 600 Watts. The client was going to use it for radio in Ford cars.

There are plenty company making step down (buck) dc-dc converters, usually reduce 24v/48v to 12v, with maximum 500W output. But a step up (boost) one is not that easy to find, needless to say a 600W one.

Miniature Power DC/DC Converter for Serial Communication

Origin: Current-logic.com

Serial communication bus transmit data through physical network such as the RS-232, RS-485 and Controller Area Network (CAN) . The applications cover industrial process control, power supply regulation (regulators), as well as point-to-point communications between computers.

These interconnected systems are equipped with their own power supply, and the distance between the systems are often far away. For this reason, we often need to take electrical isolation measures to ensure the physical security of the system, and the need to cut off the ground loop to protect system from high voltage surge impact and reduce signal distortion.

Isolation can protect the system from surge or high voltage and high current damage caused by ground loop, which is most likely to occur when there are a number of ground access in the system . The system is connected by a long cable, and their potential to may not be the same, so current will occur between the two systems. If not isolated, this current will cause noise in the system to reduce the measurement accuracy and even destroy system components.

In industrial environment, the motor start-up and shut down, electrostatic discharge or lightning strikes will generate current through the inductive coupling in the long-distance cables, causing potential rapid change. Such changes can be up to hundreds of kilovolts. If there is no isolation measures taken, the signal or even the system will be damaged. If all the devices connected to bus share the same reference ground, then the system will be free from the impact of this destructive energy, and the isolation between devices can prevent ground loops and the occurrence of surge.

CAN bus typically uses a working voltage of 3V or 5V. In certain areas of industrial control, due to the complexity of the situation, there is high common-mode voltage between each node. Although the CAN bus has a certain anti-interference ability of common interference. However, when the common-mode voltage is higher than the threshold voltage of the receiver, the receiver can not work on, or even chips and equipments will be burned.

In order to achieve complete isolation of systems, all signal lines and power supplies must be isolated. Using isolated DC / DC converter can provide power supply isolation. Current-logic.com offers a wide selection of low cost miniature power DC-DC Converter from 0.1 watt to 2 watts.

Low-voltage DC-DC converter 16-75 VDC in; 12VDC @ 3A out

Here are some pics of the low-voltage converter that I created using the National Semiconductor LM2576HVT-12-ND buck-converter. The chip pretty much did everything for me -- all I had to do was to add two power-smoothing caps, a blocking diode, and a RF choke (which I mistaking undersized; promptly blew up and which I jerry rigged a loop of wire).
