GPS-1850D.

The GPS-1850D from GW Instek is a GPS series single output 90W linear DC power supply with 3 digits 0.5" digital LED display. It features overload and reverse polarity protection as well as high regulation and low ripple/noise that are maintained at 0.01% and <lt/> 1mVrms, respectively. Continuous or dynamic internal load selection accommodates applications such as pulsed current. Remote control terminals offer programming and operation from an external device. The power supply operates in constant voltage (CV) and constant current (CC) modes. It has line regulation ≤ 0.01% + 3mV (CV), ≤ 0.2% + 3mA (CC), load regulation of ≤ 0.01% + 3mV (current ≤ 3A), ≤ 0.01% + 5mV (current <gt/> 3A) (CV) and ≤ 0.2% + 3mA (CC). The ripple & noise is ≤ 0.5mVrms 5Hz ~ 1MHz (rating current ≤ 3A), ≤ 1mVrms 5Hz ~ 1MHz (rating current <gt/> 3A) (CV) and ≤ 3mArms ripple current (CC). It has insulation resistance of 20Mohm or above (DC 500V, chassis and terminal), 30Mohm or above (DC 500V, chassis and AC cord).

Warnings

Voltages more than 60VDC are a lethal shock hazard to user. Careful when connecting power supplies in series to achieve voltages higher than 60VDC or 60VDC between any connection or earth ground. To avoid damaging the power supply, don’t use it in a place where ambient temperature exceeds 40°C.
