Product overview
The KST A15-1812-3 from KST Meizhou Company Limited is an aircraft servo for angular actuation. Its physical integration envelope is defined by a case measuring 35.5 × 15 × 32.5 mm, with a stated dimensional tolerance of ±0.2 mm, and a weight of 50 g ±10%. Electrical integration requires a DC6.0V–8.4V supply range, with DC7.4V as the rated voltage. At 7.4V, rated current is 0.92A and stalling current is 2.85A, providing distinct current figures for those operating conditions.
At 7.4V, the servo has a rated torque of 0.5 N.m and a stalling torque of 1.8 N.m. Its speed specifications distinguish no-load movement, at 0.12 seconds per 60°, from rated movement, at 0.18 seconds per 60°; both apply at 7.4V and 25 °C. Angular travel depends on the input pulse range: 1000–2000 us corresponds to ±50°, while 500–2500 us corresponds to ±100°. The operating temperature range is -10 °C to +65 °C, defining the stated thermal limits for integration.
