TECHNICAL SPECIFICATIONS
Typical specifications @ 25
C ambient, +HV = +55VDC. Load = 200µH. in series with 1 ohm unless otherwise specified.
OUTPUT POWER
Peak power
Unidirectional 10A @ 50V for 0.5 second, 500W
After direction change ±10A @ 50V for 1 second, 500W
Continuous power ±5A @ 50V, 250W
OUTPUT VOLTAGE Vout = 0.97HV -(0.4)(Iout)
MAXIMUM CONTINUOUS OUTPUT CURRENT
Convection cooled, no conductive cooling ±2A @ 35°C ambient
Mounted on narrow edge, on steel plate, fan-cooled 400 ft/min ±5A @ 55°C
LOAD INDUCTANCE
Selectable with components on header socket 200 µH to 40mH (Nominal, for higher inductances consult factory)
BANDWIDTH
Small signal -3dB @ 2.5kHz with 200µH load
Note: actual bandwidth will depend on supply voltage, load inductance, and header component selection
PWM SWITCHING FREQUENCY
25kHz
ANALOG INPUT CHARACTERISTICS
Reference Differential, 20K between inputs with standard header values
GAINS
Input differential amplifier X1 as delivered. Adjustable via header components RH6, RH7
PWM transconductance stage 1 A/V ( output vs. input to current limit stage )
OFFSET
Output offset current ( 0 V at inputs ) 20 mA max. ( 0.2% of full-scale )
Input offset voltage 20 mV max ( for 0 output current, RH6,7 = 10k )
LOGIC INPUTS
Logic threshold voltage HI: 2.5V , LO: 1.0V, +5V Max on all logic inputs
/Enable LO enables amplifier (/Enable Pol open) , HI inhibits; 50 ms turn-on delay
/POS enable, /NEG enable LO enables positive and negative output currents, HI inhibits
/Reset LO resets latching fault condition, ground for self-reset every 50 ms.
/Enable Pol (Enable Polarity) LO reverses logic of /Enable input only (HI enables unit, LO inhibits)
LOGIC OUTPUTS
+Normal HI when unit operating normally, LO if overtemp, output short, disabled, or power supply (+HV) out of tolerance
HI output voltage = 2.4V min at -3.2 mA max., LO output voltage = 0.5V max at 2 mA max.
Note: Do not connect +Normal output to devices that operate > +5V
INDICATORS (LED's)
Normal (green) ON = Amplifier enabled, no shorts or overtemp, power within limits
Power fault (red) ON = Power fault: +HV <18V OR +HV > 55V
Short/Overtemp (red) ON = Output short-circuit or over-temperature condition
CURRENT MONITOR OUTPUT 5V @ 10A (2A/volt), 10k , 3.3nF R-C filter
DC POWER OUTPUTS
+5VDC 30mA (Includes power for Hall sensors)
+15VDC 10mA
Total power from all outputs not to exceed 200mW.
PROTECTION
Output short circuit (output to output, output to ground) Latches unit OFF (self-reset if /RESET input grounded)
Overtemperature Shutdown at 70°C on heatplate (Latches unit OFF)
Power supply voltage too low (Undervoltage) Shutdown at +HV < 18VDC (operation resumes when power >18VDC)
Power supply voltage too high (Overvoltage) Shutdown at +HV > 55VDC (operation resumes when power <55VDC)
POWER REQUIREMENTS
DC power (+HV) +18-55 VDC @ 10A peak.
Minimum power consumption 2.5 W
Power dissipation at 5A output, 55VDC supply 10W
Power dissipation at 10A output, 55VDC supply 40W
THERMAL REQUIREMENTS
Storage temperature range -30 to +85°C
Operating temperature range 0 to 70°C baseplate temperature
MECHANICAL
Size 3.27 x 4.75 x 1.28 in. (83 x 121 x 33mm)
Weight 0.52 lb (0.24 kg.)
