PIM-Mini-200 Pulsed Current Source Datasheet Precision Pulse Control The Mini-200 is a compact and lightweight pulsed current source designed to drive laser diodes, bars, arrays, or any low-impedance load. The key 200 A, 25 V compliance, 20 Hz, 200 s pulse width specifications are output current from 25 A to 200 A, rise and fall times below 10 s at 200 A, pulse widths from 25 s to 250 s, forward voltage from 0 V to 48 V, and pulse repetition rate from single shot to 200 Hz. System Operation The Mini-200 output current may be set with an internal potentiometer or an analog voltage. The pulse width is controlled with the input trigger signal. The system requires two DC voltages for operation, 12 V and compliance voltage equal to 12 V above the laser diodes forward voltage. Output Cable The laser or load is connected to the Mini-200 with 22 AWG twisted pair cable (included) with a length of 15 cm (6 inches) or less. 100 A, 19 V compliance, 20 Hz, 200 s pulse width What is included Mini-200 Mini-200 Pulser DC Input Cable Output Cable Control Signal Cable Mini-200 Development Kit This development kit includes everything in the Mini- 200 (listed above) plus everything required to send single shot pulses from 25 s to 250 s to a laser with a forward voltage up to 12 V. It allows current amplitude and pulse width control via USB computer control or a color touch screen. 25 A, 14 V compliance, 20 Hz, 200 s pulse width Ordering Information Mini-200 Development Kit Mini-200 For sales information or technical questions contact your local IXYS representative or IXYS Colorado directly at: Sales: 970.493.1901or sales ixyscolorado.com Technical Support: techsupport ixyscolorado.com PIM-Mini-200 Pulsed Current Source Datasheet Pulse Amplitude 12 V Power Specifications (J1-Pin 1) Output Current Range 25 A to 200 A Voltage requirements 12 V DC 5% Setpoint Accuracy 1 % of full scale current Current requirements 0.100 A Current Overshoot < 0.1 % DC Input Connector (J2) Current Rise/Fall Time 300 s : 2 A current setpoint 5 A Connector Molex 22-12-2024 100 s : 5 A current setpoint 10 A Pin 1: DC + 55 s : 10 A current setpoint 15 A Pin 2: DC 45 s : 15 A current setpoint 20 A 40 s : 20 A current setpoint 40 A 30 s : 40 A current setpoint 60 A DC Input Power Specifications 20 s : 60 A current setpoint 80 A *1 Voltage requirements forward voltage + 12 V DC 5% 16 s : 80 A current setpoint 140 A Voltage Range 12 V DC to 60 V DC 10 s : current setpoint > 140 A Current requirements 5.0 A Polarity Positive *1 Operation of instrument outside of this voltage can cause Forward Voltage 0 V to 48 V permanent damage to the instrument and/or load.
