Custom 28 V series
ROS-RYB 120 (28 V)
28 V airframe pump rated to 0.6 MPa, declared against a duty-cycle envelope rather than a single point: 10 % → 10–15 L/h, 50 % → 60–75 L/h, 95 % → ≥ 120 L/h at 0.6 MPa.
- Flow rate≥ 120 L/h
- Outlet pressure0.6 MPa
- Supply voltage28 V DC
- Mass≤ 400 g
- 10–15 % minimum duty cycle
- 100 W, 3.9 A at 28 V
- 18 % smaller than the 220 for the same 28 V bus
Typical applications
- 28 V airframe integration
- Main or boost pump duty
- 8 000 m altitude ceiling
