30 W DC/DC voltage converter Bicker (9–36 VDC → 5 / 12 / 24 VDC)
The isolated Bicker DC/DC voltage converter with a power output of 30 W is designed for converting DC voltage in industrial applications. It provides safe and stable power for devices that require a different voltage level than what is available in the power distribution. A DC/DC converter is a suitable solution wherever you need to create a different, stable voltage level from an available DC supply without using an additional power source.
The converter accepts an input voltage of 9–36 VDC and converts it to the required output level of 5 V, 12 V or 24 VDC (depending on the variant). This allows PLC modules, sensors, communication devices, industrial routers or other electronics to be powered from a single common power source.

Frequently Asked Questions about Bicker BDCD-31VC DC/DC voltage converters
What is the Bicker BDCD-31VC?
DIN-rail DC/DC voltage converters for converting 9–36 VDC to a stable output of 5 V / 12 V / 24 VDC (depending on the variant) with a power rating of 30 W.
Where is the BDCD-31VC used?
For local power supply of communication and control modules or peripherals in control cabinets that require regulated 5/12/24 VDC (depending on the variant) even when the input supply line 9–36 VDC fluctuates, or when a galvanically isolated supply branch is required.
Can the converter be used for parallel operation or battery charging?
The converter is not intended for parallel operation or battery charging. It is designed as a regulated power source for powering electronic devices.
Why choose a DC/DC converter with galvanic isolation?
Galvanic isolation between input and output helps separate power branches with different potentials and reduces problems with ground loops and noise transfer between parts of the installation.
Why choose a DC/DC converter with an EMI filter?
A DC/DC converter with an EMI filter limits the propagation of interference along the power line and reduces the risk of instability in sensitive devices inside the control cabinet.
Which BDCD-31VC variant should be selected?
According to the required output voltage of the powered device: BDCD-3105VC (5 V), BDCD-3112VC (12 V), BDCD-3124VC (24 V).
Can the output voltage be adjusted (VR/trim)?
Yes, the 5 V and 12 V variants allow fine adjustment of the output voltage by ±10 %. The 24 V variant has a fixed output.
What temperature range does the BDCD-31VC support?
The operating temperature range is -40 to +85 °C.
The storage temperature is -55 to +125 °C
Does the converter support remote ON/OFF?
The converter has a dedicated Remote ON/OFF control input. To turn it on, a voltage of 3.5–36 V or an open circuit is required; to turn it off, 0–1.2 V.
How is the BDCD-31VC protected against input overvoltage?
The input includes protection against short overvoltage spikes. The converter can withstand 50 V for 100 ms, which helps handle short voltage impulses in a 24 V installation.
How is the BDCD-31VC protected during an output short circuit?
The converter includes short-circuit protection on the output. In case of a short circuit, it limits the output to prevent damage and automatically returns to normal operation once the fault is removed (auto-recovery).
How is the BDCD-31VC protected against low input voltage?
The converter includes input under-voltage protection (8.4 V). If the input voltage drops below this level, the converter prevents operation outside the allowed range. In practice, this means it does not attempt to operate at insufficient input voltage, reducing the risk of output instability.
How is the BDCD-31VC protected against output overload?
It includes overcurrent protection with a trip threshold in the range of 110–170 % of the nominal current. If the load exceeds this limit, the converter activates protection and prevents permanent overload.
How is the BDCD-31VC protected on the input?
The manufacturer specifies the requirement for an external fast 6 A fuse on the input, which must be installed by the user to protect the supply line (line protection). This fuse serves as line protection and as part of the overall converter protection.
How is the BDCD-31VC protected against reverse input polarity?
Reverse polarity protection is implemented using an input protection component (TVS/Zener) that creates a short circuit when the polarity is reversed. The external fast 6 A fuse installed by the user then melts, disconnecting the power supply and protecting the converter.
Up to what altitude can the converter be operated?
The maximum operating altitude is 5000 m.
