Remote Sense leads are protected against open, short and reversal. Remote On/Of The power supply is turned on with a TTL logic ‘1’ (or open) signal and turned off by a switch closure or TTL logic ‘0’ referenced to (-) sense terminal. Consult the factory for other options. Over Voltage Protection Output #1: 6.5V ± 0.5 VDC. The power supply will latch off until AC power is cycled. Over Current Protection Individual current limit on all outputs. Automatic recovery upon fault removal. Transient Response The peak output voltage excursion will not exceed 2% and will recover within 1% in 200 μsec for a 25% load step change. Power Fail Signal Upon AC input voltage removal, the power fail signal drops to logic zero at least 5msec before loss of DC output. On AC input turn-on, signal remains low until outputs are in regulation. Consult the factory for other options. N+1 Load Share Output #1 has active load sharing circuitry. Units will load share within 1.5% of Maximum Rated Load. Over Temperature Protection Thermal switch turns off power supply if overheating occurs and automatically restarts. Safety UL Recognized: UL File Number E14675 (1950 & 1012) CSA Certified: CSA File Number LR 9070-154C (C22.2 No. 234-M90, Level 6) TUV License Number: R9576031 (EN60950) (IEC950) Cooling The unit is designed to operate with 30 CFM of airflow. Output Isolation All outputs are fully isolated. www.murata-ps.com Technical enquiries - email: [email protected], tel: +1 508 339 3000 Output Voltages and Maximum Rated Loads OUTPUT #1 VOUT IMAX OUTPUT #2 VNOM IMAX/IPK OUTPUT #3 VNOM IMAX/IPK NX350-U3A ± 5V 50A ± 12V 10A/12A ± 12V 8A/10A - - NX350-U3B ± 5V 50A ± 15V 10A/12A ± 15V 8A/10A - - NX350-U4C ± 5V 50A ± 12V 10A/12A ± 12V 8A/10A ± 5V 3.0A/4.0A NX350-U4D ± 5V 50A ± 12V 10A/12A ± 12V 8A/10A ± 24V 1.5A/2.0A NX350-U4E ± 5V 50A ± 12V 10A/12A ± 12V 8A/10A ± 12V 3.0A/4.0A NX350-U4F ± 5V 50A ± 15V 10A/12A ± 15V 8A/10A ± 5V NX350-U4G ± 5V 50A ± 15V 10A/12A ± 15V 8A/10A ± 24V 1.5A/2.0A NX350-U4H ± 5V 50A ± 15V 10A/12A ± 15V 8A/10A ± 12V 3.0A/4.0A MODEL NUMBER OUTPUT #4 VNOM IMAX/IPK 3.0A/4.0A Note: Peak current ratings are for 10sec maximum.
