Frequently Asked Questions

What is SUNON DP201A?
DP201A is a SUNON DP-series AC axial cooling fan with a nominal 120 x 120 x 38 mm frame and a 220-240 VAC, 50/60 Hz supply rating. Multiple bearing, power and connection configurations share this base model number.

What is the rated voltage of DP201A?
The manufacturer specifies 220-240 VAC at 50/60 Hz. Individual technical specifications document operating voltage ranges of 185-240 VAC or 185-245 VAC depending on the complete part number.

What are the dimensions of DP201A?
The nominal fan size is 120 x 120 x 38 mm. SUNON's catalog mechanical drawing specifies an approximately 119 mm square frame, 38.5 mm depth and 104.8 mm mounting-hole center spacing, subject to the indicated drawing tolerances.

What is the rated current?
Standard DP201A configurations are listed at 0.125 A at 50 Hz and 0.110 A at 60 Hz. Documented low-power sleeve bearing versions are rated at 0.069/0.070 A, while low-power ball bearing versions are rated at 0.069/0.065 A. Confirm the suffix before selecting a current rating.

What is the power consumption?
Standard DP201A-2123HSL/HST/HBL/HBT.GN versions are specified at 20 W at 50 Hz and 19 W at 60 Hz. Low-power .S.GN versions are specified at 10.8 W and 10.4 W respectively. These are different configurations, not interchangeable ratings for a single fan.

What is the rated fan speed?
The standard sleeve bearing versions are rated at 2550/2900 RPM and standard ball bearing versions at 2750/3050 RPM for 50/60 Hz. Low-power sleeve bearing versions are rated at 2550/2300 RPM, while low-power ball bearing versions are rated at 2550/2550 RPM.

What airflow does DP201A provide?
Standard sleeve bearing variants provide 85/105 CFM at 50/60 Hz, while standard ball bearing variants provide 87/107 CFM. Documented low-power sleeve bearing variants provide 85/78 CFM and low-power ball bearing variants provide 85/85 CFM.

What is the maximum static pressure?
The standard sleeve bearing variants are rated at 0.25/0.30 inH2O and standard ball bearing variants at 0.26/0.32 inH2O for 50/60 Hz. Low-power sleeve bearing versions are specified at 0.25/0.13 inH2O and low-power ball bearing versions at 0.25/0.25 inH2O.

Does SUNON DP201A use sleeve or ball bearings?
Both bearing systems are available. HSL and HST configurations use sleeve bearings; HBL and HBT configurations use ball bearings. The complete SUNON part number is required to identify the correct type.

What is the acoustical noise level?
The standard sleeve bearing models are rated at 43/48 dB(A), while standard ball bearing models are rated at 45/50 dB(A) for 50/60 Hz. Low-power versions have different documented noise ratings, so the individual suffix must be checked.

How is DP201A electrically connected?
Manufacturer documentation includes two-wire lead and two-terminal configurations. The L suffix indicates a wire-lead version, while T indicates a terminal version. The catalog drawing shows 24 AWG wiring for lead configurations and an M4 grounding point. Electrical installation must follow applicable mains-voltage safety, grounding and circuit-protection requirements and should be performed by qualified personnel.

What should be checked before ordering DP201A?
Confirm the complete SUNON DP201A part number, 220-240 VAC supply, 50/60 Hz frequency, standard or low-power configuration, sleeve or ball bearing type, 120 x 120 x 38 mm nominal dimensions, 104.8 mm mounting-hole spacing, two-wire or terminal connection, mounting orientation, protective grounding and required cooling performance. In particular, DP201A-2123HBL.GN and DP201A-2123HBL.S.GN have significantly different power and airflow characteristics. Do not substitute one version for another without confirming the electrical and mechanical requirements of the equipment.
