TDK-Lambda converters and power supplies

Connecting a series of power supplies to AC circuits is not an optimal solution. That is why many manufacturers offer AC/DC converters, designed for mounting in fuse boxes and switch cabinets, allowing the main DC circuit to be set and a series of receivers to be connected to it. Some of the solutions in this category are offered by TDK-Lambda.

The products presented below can be divided into two groups. The first one consists of AC/DC fixed installation power supplies with relatively high-power rating and a wide range of input voltages (mains AC), which produce standard DC voltages (12V, 24V etc.). They are designed for DIN rail mounting and easy connection to typical systems. The second group consists of miniature DC/DC converters thanks to which the power supplied from the main DC circuit can be adjusted to the requirements of electronic components applied in controllers, control panels, communication devices, etc. Most of the items presented here are available directly from TME warehouses. TME recommend this offer to maintenance departments, installers, electrical engineers, and manufacturers of electronic devices.

1.5W and 3W CCG converters

Miniature DC/DC converters of the CCG1R5 and CCG3 series measure 15.7mm by 10.4mm (with 11.5mm height above the PCB surface). They feature leads for THT mounting and are enclosed in cases protecting them from mechanical damage and particle penetration that could lead to short-circuit (the component circuit is placed on a double-sided, densely filled laminate plate). Depending on the series, the converters deliver output power of 1.5W or 3W (information contained in the reference number: xxx1R5 or xxx3). They can have one or two outputs. The former models allow adjustment of the VOUT value (-5…+10%) using a dedicated pin. The latter ones are designed to generate symmetrical voltage (-12V or -15V DC) of up to 250 mA (depending on the model).

CCG converters perfectly meet the needs of compact devices

Moreover, the converters offer a wide range of power supply parameters: from 4.5…18V to 18…76V DC. With such electric characteristics, the CCG series is ready to work in many types of circuits: sensor controllers, microcontroller systems, preamplifier, or oscillator circuits and in similar applications in the fields of radiocommunication or measuring equipment.

DRL series power supplies

The openings at the top and the bottom of the body provide efficient cooling

DRL power supplies are low-profile AC/DC devices intended for DIN rail mounting. Their main fields of application include industrial installations and building automation, they can also be used in Smart Home installations and other systems requiring 12V or 24V DC power supply. They are equipped with typical elements: connection points in the form of terminal blocks, LED output voltage indicator placed on the front panel, and (in the case of selected models) an opening for setting the desired output parameters (12–15V or 24–28V DC). The power supply outputs are NEC () Class 2 compliant.

TME offers 10W, 30W, 60W and 100W products, which satisfy the needs of numerous applications. The products have been adapted to mains supply and, regardless of the standard applicable in a given country, they can be supplied with a voltage ranging from 85V to 264V AC (they do not require connection to a protective earthing). A significant feature of these items is their tolerance to a wide range of ambient temperatures (from -40°C to 85°C) and air humidity (up to 95%).

DRB series of power supplies

When searching for AC/DC power supplies with the widest scope of capabilities, it is worth considering the impressive parameters of theDRB series. The series is designed for a single-phase or three-phase current (depending on the model) in the range of 85–264V AC to 350–575V AC with a frequency of (53…63Hz). The DRB series products produce output voltages of 5V, 12V, 24V or 48V DC.   

The DRB power supplies can operate with high-capacitance loads, they are adapted to increased inrush currents (120% for up to 2 sec.). Moreover, they feature a parallel work mode (activated with a switch placed on the front panel), in which they can supply power with multiplied output rating (when several units are connected). The products are characterised by low losses in the stand-by mode and thus are suitable for installations based on renewable energy sources. 

Additionally, it should be noted that the power supplies are equipped with a range of protections, including but not limited to a smart output voltage limiter (minimising the risk of damaging sensitive electrical loads) or short-circuit protection. The DRB products have countless certificates and comply with many norms applicable in North America, Europe, and the UK (IEN61010, E356563, UL62368, UK CA, EAC). With all these features, the TDK-Lambda offer meets the requirements of power supplies operating in industrial automation systems, semiconductor manufacturing, communication, and green energy, etc.
