Optional CH4 polarity	The listed standard CH4 output is −12 V. A positive CH4 configuration is optional and requires consultation with MEAN WELL before delivery; it is not the stated standard configuration.

Protection and operating conditions

Short-circuit and overload protection	Short-circuit protection is listed among the series features. Overload operates at 105–150% of rated output power, with constant-current limiting and automatic recovery after the fault condition is removed.
Overvoltage protection	CH1: 5.75–6.75 V; CH2: 3.8–4.4 V. Output voltage shuts down; cycle input power to recover.
Overtemperature protection	Output voltage shuts down and recovers automatically after temperature falls.
Cooling	Forced-air cooling by the built-in DC fan. Maintain the airflow direction and clear ventilation openings shown in the mechanical drawing.
Operating temperature	−10 to +60°C, subject to the horizontal-mounting derating curve.
Ambient-temperature derating	For this model, the horizontal curve permits 100% load from −10 to +50°C, falling to 70% at +60°C. Apply input-voltage derating as well.
Input-voltage derating	At 60 Hz, the curve shows 70% load at 90 V AC, increasing to 100% at 115 V AC and remaining at 100% through 264 V AC. Apply the temperature limit at the same time.
Humidity and storage	Working humidity: 20–90% RH, non-condensing. Storage: −20 to +85°C and 10–95% RH, non-condensing.
Temperature coefficient	±0.03%/°C over 0–50°C.
High-altitude derating	For this fan-cooled model, above 2000 m reduce the permitted ambient temperature by 5°C per additional 1000 m.
Vibration	10–500 Hz, 2G; 10 minutes per cycle and 60 minutes each along the X, Y and Z axes.

Installation and system integration

Safe installation and servicing	Install this component power supply inside the end-system enclosure. Disconnect the system from the mains before installation or maintenance and prevent accidental reconnection. Keep it away from high moisture, water and fire sources. Have faults examined by a qualified technician; do not remove the power-supply case yourself.
Ventilation and mounting	Keep the built-in fan and all ventilation openings unobstructed. Maintain 10–15 cm clearance when an adjacent device is a heat source. Non-standard mounting orientation or high ambient temperature may require further output derating. Follow the model drawing for mounting-screw penetration and maintain insulation clearance from internal components.
Power-terminal tightening and earthing	The installation manual lists M3.5 input/output terminal screws for QP-200, with a suggested tightening torque of 8–10 kgf·cm. Connect AC/L to live, AC/N to neutral and FG to protective earth, following the model terminal assignments. Secure every conductor strand and connection. Generic enclosure-material torque tables do not replace the QP-200 terminal values.
Conductor selection	Select conductors for the actual continuous and permitted peak currents, temperature, installation and terminal capability. The manual wire guide lists 18/16/14/12/10/8 AWG with 0.75/1.00/1.5/2.5/4/6 mm² and respective current bands of 6/6–10/10–16/16–25/25–32/32–40 A. With five or more wires connected to the unit, derate each wire to 80% of the guide current. The guide ends at 40 A; do not extrapolate beyond its stated range.
Continuous and peak loading	Keep continuous output within each channel current range, the model total-power rating and applicable input, ambient-temperature and altitude derating limits. The listed peak currents require a maximum duty cycle of 33.3% within every 30 seconds, with average output power no greater than the model-rated power. A peak-current value is not a continuous-current rating.
Complete-system EMC verification	Verify EMC again with the power supply installed in the final equipment and connected to a representative load. Wiring, assembly and the application affect the result. The QP-200 datasheet records a 360 × 360 × 1 mm metal plate for its component EMC test; this is a test arrangement, not a supplied accessory or an installation-clearance requirement. The linked EMI guidance supports system testing and does not certify the finished equipment.
