DC Motor Speed Control, 120/240VAC Dual Supply Voltage, 50/60Hz, 0-90/180VDC, 2 Amp, 1/50-1/8hp (90V), 1/25-1/4hp (180V), (No Acceleration/Deceleration Adjustments), Open Chassis, with Terminal Strip, 150 Series

The 150D Series from Dart Controls sets a new standard for SCR drive design. Available in Chassis (15x-C) or NEMA 4X enclosed (15x-E) 151 models are 120VAC supply voltage/0-90VDC motor voltage 153 models are 120VAC supply voltage/0-90VDC motor voltage - 240VAC/180VDC Models with a 'D' include motor field supply, ACCEL/DECEL adjustments and power/current limit LED's (L series do not) The 150D Series was developed with standard features and convenient options required for most applications. The 150D Series is also a drive designed with the future in mind – a development platform which will soon incorporate new features not found anywhere else in the market. The 150D Series is a superior choice for new and existing applications – it will directly replace other drives on the market without changing mounting dimensions or wiring terminations. The state-of-the-art Surface Mount Electronics offers a circuit that is flexible and responsive, with high power density in a small footprint. Dart’s adjustable HP design eliminates the need to manage clumsy HP resistors. In the open chassis model, two wiring terminations are available – spade terminal (standard) and euro-style terminal strip. Fusing options allow for fusing AC line, motor armature, or both; all at the user’s discretion. For OEM’s with ex-US sales, some models offer 90VDC output with either 120 or 240VAC supply voltage. The printed circuit board has been designed to add components to support single or multiple fixed speeds using a switch input. PCB board sockets allow for the development of specific, custom options the OEM may require. Board mounted LED’s verify the presence of supply voltage, and whether the drive is in an over-current condition. The -HSK auxiliary heat sink doubles the HP capacity when larger motors are used. An important feature of the -HSK is it uses the SAME mounting hole pattern as the base control, with a modest 4.25″ x 4.25″ space conscious footprint.
