We suggest the 𝑠𝑢(1, 𝑁 |𝑀)-superconformal mechanics formulated in terms of phase superspace given by the non-compact analog of complex projective superspace CP 𝑁 | 𝑀 . We parameterized this phase space by the specific coordinates allowing us to interpret it as a higher-dimensional super-analog of the Lobachevsky plane parameterized by lower half-plane (Klein model). Then we transited to the canonical coordinates corresponding to the known separation of the "radial" and "angular" parts of

... conformal mechanics. Relating the "angular" coordinates with actionangle variables we demonstrated that the proposed scheme allows constructing the 𝑠𝑢(1, 𝑁 |𝑀) superconformal extensions of a wide class of superintegrable systems. We also proposed the superintegrable oscillator-like system with a 𝑠𝑢(1, 𝑁 |𝑀) dynamical superalgebra, and found that it admits deformed N = 2𝑀 Poincaré supersymmetry.
