DC/DC converter 48V bidirectional, 100A, 5kW
DDL4848-48
This member of the Querom 48V DC/DC converter family connects an energy storage system bidirectionally to a supply grid. A comprehensive software package precisely defines when the grid charges the storage system. It also determines when the storage system supports the grid. The controllable, current-limited charging process of the 48V DC/DC converter optimises the charging and discharging of various battery storage systems or supercap modules. To simplify the system, the DC/DC converter also provides a 24V output with 150W. This supplies control electronics such as PLCs. The package is rounded off by the high power density and an efficiency of up to 98.5%. Useful telemetry functions also support system diagnostics.

Product features
Hardware
The DDL4848-48 is a non-isolated low-voltage, high-power DC/DC converter. It enables bidirectional power transfer between two ports, port A and port B. When transferring power from port A to port B, the converter operates in downward mode. It supplies a reduced voltage level to port B. In the opposite direction, the converter operates in upward mode and increases the voltage level at port A. Port C, which is in parallel with port A, contains a circuit for limiting the inrush current.
24V output: An additional 24VDC output with 150W power can be used to supply connected control units, fans or sensors.
CAN bus system: The CAN bus system can be fully configured by the user, allowing all parameters to be set and all measured values and status messages to be queried.
Sleep pin: The converter has a configurable sleep mode function to minimise the energy requirement during maintenance work or idle times.
Sense line: In addition, the connected energy storage system can be monitored using sense lines and the energy flow adjusted accordingly.
Housing: Integration into other housings possible.
Cooling: Contact cooling due to high efficiency.
Safety: Overtemperature, open-circuit and short-circuit proof.
Example of operating modes – AGV
Charge – Charging energy storage
Source (Port C) –> Storage (Port B)
Recuperate -bidirectional energy flow
Drive (Port A) <–> Storage (Port B)
Supply – Drive supply
Storage (Port B) –> Drive (Port A)
Software
The DDL4848-48 comprises a comprehensive software package with a modular structure in terms of various functions.
Real-time diagnostics: Retrieve various measured values such as voltage, currents and temperatures. In combination with status and error messages, a user or a higher-level control system can carry out a comprehensive diagnosis of the process and react to various events.
Setpoints: The user can set various parameters via the communication interface as a factory setting or during operation. In addition to current and voltage regulation, threshold values and limits can also be parameterised.
Interface: The CAN2.0B bus, which is available as standard, can also be customised during operation. This allows the user to independently adjust the baud rate and ID length as well as the identifiers of the frames. The cyclical behaviour of individual frames can also be adjusted.
Options: Customer-specific charging and trickle charging functions, a special event, triggered behaviour, handling of short circuits and overloads or derating (power reduction) in the event of overtemperature can be implemented with very little effort.
