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

2 Compatible with single-output (NMS-240) and dual-output (NMD-240) modules for flexible voltage/current configurations

3 Supports global ON/OFF control (via RC1 pin and GND-P) and local ON/OFF control for individual modules (via RC2/RC3 pins and GND)

4 Remote sense function (+S/-S pins) compensates for voltage drop on load wiring up to 0.5V

5 Output voltage programming (PV pin) and constant current level programming (PC pin) for precise parameter adjustment

6 DC OK signal (TTL level, 4.5-5.5V when ON, 0-0.5V when OFF) indicates module operating status

7 Temperature alarm (T-Alarm signal) provides over-temperature notification with high-level output

8 Current sharing (CS pin) enables parallel module operation to balance output current

9 Auxiliary power outputs: +5V-Aux_P (2A for NMP1K2) and Vcc2 (5V/10mA for modules)

10 Built-in protections: Over-voltage (OVP), Over-current (OCP), Over-temperature (OTP), and short-circuit protection

1 Industrial automation systems requiring multiple adjustable DC voltage outputs for sensors/actuators

2 Test and measurement equipment needing precise voltage/current control and status monitoring

3 Data centers/server racks using parallel modules for redundant high-power solutions

4 Telecom equipment racks supporting diverse components with varying power requirements

5 Embedded system development platforms requiring flexible voltage programming and remote control

6 Critical applications needing redundant power to ensure continuous operation

1 Global ON/OFF: Install the shorting connector (RC1 to GND-P) if not using external control to enable output

2 Remote sense: Use twisted-pair wires for +S/-S connections to minimize EMI

3 Parallel operation: Connect CS pins of modules, ensure voltage difference <0.2V, total power ≤1200W, use short large-diameter wires

4 Temperature derating: For Vo <12V and ambient temp -15°C to -30°C, derate current to 90% of rated value

5 Protection reset: Power cycle the unit or remove fault to restore operation after OVP/OCP/OTP triggering

6 Module installation: Ensure modules are seated firmly; blank slots need BLANK-NMS240 accessory

7 Wiring: Use appropriate wire gauges to avoid overheating and voltage drops beyond remote sense compensation
