OCEM Multicrom CCR
Italian CCR with thyristor or IGBT chopper; 2.5-30 kW.
Multicrom is OCEM's flagship CCR family, offered in thyristor (MCR) and IGBT (MCR-V) topologies across 2.5, 4, 5, 7.5, 10, 15, 20 and 30 kW ratings. The IGBT version delivers near-unity power factor and very low THD, a growing requirement as GCC airport substations tighten harmonic limits. Multicrom ships with a colour touch-screen HMI, Ethernet to ACE-class ALCMS and supports 5- or 3-step dimming to ICAO Annex 14.
