Delta Electronika extends its line-up of bidirectional sink source DC power supplies which incorporate a DC source with a grid-tied DC load in a single unit with the addition of the SM210-CP-150 (0 to 210V, -150 to +150A). With power capability of 15kW per unit, extendable to 900kW in full master/slave mode, it makes an ideal choice for engineers involved with battery & motor testing.
