Description

NID100-5 — Non-isolated regulated DC/DC converter

MEAN WELL NID100-5 is an economical open-frame, non-isolated regulated DC/DC converter in a SIP package. It provides 5 V DC with 11 A output and a rated power of 55 W from a 10.5–53 V DC input. Remote ON/OFF control, optional output trimming and free-air convection cooling support integration into equipment. Apply the model-specific input-voltage and ambient-temperature derating limits.

Control, protection and alternative connection

Remote ON/OFF Voltage is measured from R.C. to COM. ON: 1.2 V DC < R.C.–COM < 12 V DC, or an open circuit. OFF: R.C.–COM < 0.4 V DC, or a short circuit. The pin table assigns R.C. to pin 13 and COM to pins 5, 6, 7 and 8.
Optional output trim Pin 12 is Trim (optional). Confirm the supplied trim configuration and allowable adjustment range before use; the series pages do not specify a trim range or external adjustment-resistor value.
Overload protection 120–300% of rated output power, typical; hiccup mode with automatic recovery after the fault condition is removed
Short-circuit protection All outputs have short-circuit protection; hiccup mode with automatic recovery after the fault condition is removed
Overvoltage protection 6.4–7.5 V; shuts off the output voltage and clamps it with a TVS diode
Input fuse recommendation 8 A fuse, as recommended in the input specification
Negative-output connection reference The negative-output diagram connects the external positive supply to module +Vin pins 9 and 10; external −Vin and the application GND connect to module +Vout pins 1–4; the negative output −Vo is taken from COM pins 5, 6, 7 and 8. The input capacitor is positive toward external +Vin; the output capacitor is positive toward application GND. PDF page 8 states that the input voltage in this connection must be below 30 V DC. The external supply reference in this connection differs from module COM. Confirm the complete negative-output application limits and control references with MEAN WELL; the diagram does not provide a separate negative-output current or power rating.

Environment and load derating

Operating temperature and cooling −30 to +85°C, subject to the derating curves; cooling by free-air convection
Input-dependent load derating Vertical installation, free-air convection. The three curves apply to 10.5 ≤ Vin ≤ 30 V DC, 30 < Vin ≤ 50 V DC, and 50 < Vin ≤ 53 V DC, respectively. The limits through +50°C are 100%, 90% and 85% load, respectively; therefore high input voltage already requires derating below +50°C. At +85°C the plotted limits are approximately 40%, 30% and 25%. Follow the applicable curve between plotted points; do not apply a full-load temperature from another input band. The working range ends at +85°C.
Working humidity 20–85% RH, non-condensing
Storage temperature −30 to +105°C
Temperature coefficient ±0.03%/°C over 0 to +50°C
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes

Mechanical details and packing

Dimensions 50.8 × 27.5 × 12 mm (L × W × H), or 2.0 × 1.082 × 0.472 inches, in the specification table. The mechanical drawing marks the 12 mm profile as maximum.
Mechanical drawing details Front-view references: 50.8 mm overall length, 10.2 mm and 25.4 mm dimension spans, 2.54 mm local pin pitch, 0.64 mm pin width and 1.3 mm edge offset. The front view shows 4.5 mm lead projection; the side view shows a 4 mm horizontal pin offset. The drawing gives a general tolerance of ±1 mm (±0.04 inch). The additional side-view span is printed as 9 mm [0.315 inch]; these two units are inconsistent. Confirm that detail against the supplied unit before using it for a tight mechanical fit.
