Power sharing Features High isolation 3kVDC & 4kVDC for 1 second Efficiency up to 87% DC/DC Converter Wide operating temperature range from Unregulated -40C to +85C UL60950 certified Converters RKZ-xx2005D IEC/EN60950-1 certified Description 2 Watt The RKZ-xx2005D series features DC/DC converters which are especially designed for SiC mosfet SIP7 for drivers. The modules are available with input voltages of 5, 12, 15, or 24VDC with two asymmetric outputs of +20VDC and -5VDC. A special feature of this converter is output power SIC Application sharing: the RKZ-xx2005D can be used with equal power (asymmetrical current) or equal current (asymmetrical power) loads. The modules offer 3kVDC or 4kVDC isolation. The operating temperature range of -40C to +100C (with derating) meets harsh environmental requirements. Selection Guide Part nom.
