This member of the Querom low voltage family makes it possible to connect an energy storage system bidirectionally to a supply grid. A comprehensive software package makes it possible to define exactly when the energy from the supply grid is used to charge the storage system and when the storage system supports the supply grid. To simplify the overall system, the converter offers an additional 24V output with 150W for supplying PLCs. The package is rounded off by the high-power density, the exceptionally high efficiency of up to 98.5% and useful telemetry functions for system diagnostics.
Charge battery
Current-limited charging function
Efficient
Up to 98.5% efficiency
Recuperation
Energy recovery during braking
Compact
182*138*45mm³
Recuperation
The DC/DC converter controls the energy flow in both directions with up to 100A. Bidirectionality allows energy to be fed back during braking or discharging processes and increases the efficiency of the application.
Charging function
The controllable current-limited charging function of the converter allows various battery storage systems or supercap modules to be charged and discharged in an optimum manner.
Additional 24V output
An additional 24VDC output with 150W power can be used to supply connected control units, fans or sensors.
Energy-saving
The converter has a configurable sleep mode function to minimise energy requirements during maintenance work or idle times.
CAN bus system
The CAN bus system is fully configurable by the user and allows all parameters to be set and all measured values and status messages to be queried.
Safety functions
The converter is overtemperature, open-circuit and short-circuit proof. In addition, the connected energy storage device can be monitored using sense lines and the energy flow can be adjusted accordingly.
Areas of application: AGVs
DDL3050-48 – Adjustable DC/DC converter
Highly efficient, controllable DC/DC converter for supplying loads with constant voltage or current. (Download data sheet: short version / long version)
With this derivative from the Querom LV platform, you can connect loads that require a clean supply with constant voltage to a supply network with variable voltage. Thanks to the constant current behaviour of the converter, with a current setpoint that can be defined in real time via analogue input or software, it can be paralleled if required or used to charge batteries, for example. The special design of the electronics allows operation with full current up to input voltage equal to output voltage (100% duty cycle).
Cooling
Contact cooling via base plate
Efficient
Up to 98.5% efficiency
Security
Open-circuit, short-circuit and overtemperature-proof
Compact
182*138*45mm³
Controllable current
The current value of the current limitation can be set between 10A and 60A via an analogue input (0-5V) or software command via the existing bus system.
100% Online
The Querom circuit design, which does not require any critical special ICs, enables operation with the full specified current of 60A, while the input voltage is only a few tens of millivolts above the output voltage.
Precise
The converter’s 16-bit measuring system allows the power converted in the load to be monitored precisely and controlled via the voltage and current setpoint specifications. The current measurement does not leave a corridor of 1% around the true value, while the voltage measurement has a maximum deviation of 0.5%.
Inrush current limiter
The integrated inrush current limiter has a firm grip on generally problematic switch-on processes on the DC supply network and solves problems with peak currents to be protected and inductive voltage surges without external additional components.
