产品特点 FEATURES

1 Modular power supply design with 6 slots for NMP1K2 model, supporting up to 1200W total output power

2 Wide input voltage range: 90~264VAC or 120~370VDC, adaptable to various power grids

3 High efficiency up to 91% (typical) at full load with H/K modules (24V/48V nominal)

4 Complies with multiple safety standards including medical (2x MOPP between primary and secondary) and ITE standards

5 Multiple protection functions: overload (constant current limiting), overvoltage (shut down and recover on re-power), overtemperature (shut down and auto-recover after cooling)

6 Supports remote control: global ON/OFF (via RC1) and local ON/OFF (via RC2 for each module)

7 Auxiliary power output:5V@2A (NMP1K2) for external control circuits

8 Current sharing capability for parallel operation of modules, ensuring balanced load distribution

9 Remote sense function to compensate voltage drop on load wiring up to 0.5V

10 Output voltage programming (PV pin) and current programming (PC pin) for flexible configuration

11 DC OK signal (TTL level) to indicate module output status; T-alarm signal for over-temperature warning

12 Low leakage current (<400uA at 264VAC) and inrush current control

使用场景 APPLICATIONS

1 Industrial automation systems requiring multiple voltage outputs

2 Medical equipment that meets 2x MOPP safety requirements

3 Test and measurement instruments needing stable and configurable power supplies

4 Communication base stations and network equipment

5 Industrial control panels and modular electronic systems

6 Parallel operation setups for high-power applications (up to 6 modules in parallel for NMP1K2)

7 Laboratory equipment and R&D prototyping platforms

8 Data centers and server racks with modular power needs

注意事项 PRECAUTIONS

1 Follow recommended mounting torque (12Kgf-cm for AC input terminal,10Kgf-cm for DC output terminal) and screw sizes (M4 for mounting, M3.5 for output terminals)

2 Derate output current to90% of rated value when output voltage <12V and ambient temperature is between -15°C and -30°C

3 Ensure the shorting connector (from RC1 to GND-P) is installed if global ON/OFF control is not used; otherwise, the power supply will have no output

4 Use compatible connectors: HRS DF11 series for control pins (CN32, CN81)

5 When paralleling modules, ensure output voltage difference between modules is <0.2V; do not exceed total power limit (1200W for NMP1K2)

6 Do not use the current programming (PC) function when modules are in parallel operation

7 Properly wire remote sense pins (+S/-S) to compensate for voltage drop; use twisted pairs for sensing lines

8 Avoid exposing the power supply to condensing humidity; operating humidity range is20~90% RH non-condensing

9 Follow ESD protection measures during installation and maintenance to prevent damage to electronic components

10 Do not operate the power supply beyond specified ambient temperature range (-30~+70°C) without proper derating

11 When using current sharing, connect CS pins of all parallel modules and ensure wiring is short and of large diameter
