Increase the 5mm to 15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%, the 5mm can be reduced to zero. The device is designed, tested and approved for branch circuits up to 50A without additional protection device.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 3. DC-INPUT The input can be powered from batteries or similar DC sources and must be a PELV or SELV source or an "Isolated Secondary Circuit" in order to maintain a SELV or PELV output. Check for correct input polarity. The device will not operate when the voltage is reversed. DC input DC input range Allowed voltage between input and earth/ground Allowed input ripple voltage Nom.

PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series Requirements for the Supplying Source In certain circumstances, the input filter of the DC/DC converter can show a resonant effect which is caused by the supplying network. Especially when additional external input filters are utilized, a superimposed AC voltage can be generated on the input terminals of the DC/DC converter which might cause a malfunction of the unit. Therefore, additional input filters are not recommended.

INPUT INRUSH CURRENT An active inrush limitation circuit (inrush limiting NTC resistor which is bypassed by a MOSFET) limits the input inrush current after turn-on of the input voltage. The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on. Inrush current Max. Typ. Max.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 6. OUTPUT The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage and is designed to supply any kind of loads, including unlimited capacitive and inductive loads. The output is electronically protected against overload, no-load and short-circuits. In case of a protection event, audible noise may occur. Output voltage Adjustment range Nom. Min. Max.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 7. HOLD-UP TIME The input side of the DC/DC converter is equipped with a bulk capacitor which keeps the output voltage alive for a certain period of time when the input voltage dips or is removed. The bulk capacitor can be discharged by loading the DC/DC converter on the output side or through a load which is parallel to the input. There is no protection in the DC/DC converter which prevents current from flowing back to the input terminals.

YRM2.DIODE - REDUNDANCY MODULE The YRM2.DIODE is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems. The device is equipped with two input channels each 10A nominal, which are individually decoupled by utilizing diode technology. The output can be loaded with nominal 20A. The device does not require an additional auxiliary voltage and is self-powered even in case of a short circuit across the output.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 22. APPLICATION NOTES 22.1. PEAK CURRENT CAPABILITY The unit can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents. This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 22.2. OUTPUT CIRCUIT BREAKERS Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and may also be used on 48V branches. MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.
PRELIMINARY CD-Series CD10.482 DC/DC Converter 48V/48V, 5A, 240W 22.4. SERIES OPERATION Unit A Devices of the same type can be connected in series for higher output voltages. It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc must be installed with a protection against touching. Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 22.6. PARALLEL USE FOR REDUNDANCY 1+1 Redundancy: Devices can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case one device fails. The simplest way is to put two devices in parallel. This is called a 1+1 redundancy. In case one device fails, the other one is automatically able to support the load current without any interruption.
PRELIMINARY CD10.482 DC/DC Converter 48V/48V, 5A, 240W CD-Series 22.7. USE IN A TIGHTLY SEALED ENCLOSURE When the device is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In such situations, the inside temperature defines the ambient temperature for the device. In the following test setup, the device is placed in the middle of the enclosure; no other heat producing items are inside the enclosure. The load is placed outside the enclosure.

MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The listed lifetime and MTBF values from this datasheet apply only for the standard mounting orientation. The following curves give an indication for allowed output currents for altitudes up to 2000m (6560ft). Fig.
