DC SPECIFICATIONS
Output 
     Current
-Standard models from 2A to 1 0OOA. 
     Voltage - Standard models from 4V to 1 0V. Other models available upon       request.

Input-Various Input voltage options are available in the range of 100VAC-                 480VAC. S0/60Hz, 
           single or 3-phase, depending on output power rating. 

Regulation 
     Constant Voltage Mode - An output current load change of 100% will              cause a voltage variation of less than 0.1 %. 
     Constant Current Mode - An output voltage load change of 100% will              cause an output current change variation of less than 0.1 %. 
     line Effects - Variations in the regulated output will not exceed 0.1 % of            the output for low line to high line AC input changes. 
     Ripple-Typically S l00mV (1% - 2%) maximum with a resistive load and              the power line within the specified range. Maximum ripple typically                occurs at 100% of rated power.
     Stability- Maximum deviation in either voltage or current for an eight (8)          hour period is 0.05% under conditions of constant line, load and                        temperature. 
     Temperature Coefficient- The output current temperature coefficient is          0.03%/   °C of the rated output current. 

Cooling 
     All BTA power supplies are forced air cooled and capable of continuous         full power operation at ambient temperatures, between 0°C (32°F) and           50°C (122°F). For operation from S0°C to 70°C the derating factor is 1 %             per °C for all models. Units may be safely stored at temperatures of                 -55°C to +85°C. 

Controls 
     Local- All BTA models are provided with a U.l. listed circuit breaker or             switch and fuse (Sl kW) which combines primary circuit protection                   with on/off control. Output voltage/current adjust­ment is via 10-turn               potentiometers located on the front panel. Simultaneous indication of           output current and voltage is provided by standard digital front panel             meters. 
     Remote
     All BTA power supplies are also remotely controllable via analog i/o                located on the rear of the unit. Various control signal options are                      available. Digital controls options are avail­able on some models. 
     Remote Enable/Interlock - All BTA models are capable of being                      remotely started or stopped by means of an external AC or DC voltage          source, or a dry contact closure. 

Protective Circuits 
     Overvoltage - Overvoltage protection, adjustable from the front panel is         standard on all BTA models. This circuit will disable the output if it                   exceeds the preset value. Primary power must be cycled to reset. 
     Over Temperature Protection - Automatic protection against excessive            temperatures is standard on all models. 
     AC Inrush - Soft start is standard on all BTA models. line current is less            than That at full load during turn-on, turn-off, power interruption or                  reapplication.
