Switching Power Supply, Power Rating 50 W, Temperature Coefficient 0.03 %⁄°C
** General Specifications
Input Protection:* Internal AC fuse provided on all units.
** Inrush Current:** Inrush is limited by internal thermistors. The inrush at 240 VAC averaged over the first AC half-cycle under cold start conditions will not exceed 37 A.
** Temperature Range:** 0 to 50°C at full rated power.
** EMI Compliance:** All models include built-in EMI filtering to meet or exceed the emissions requirements of FCC 20870 Class B, CISPR22-Class B and VDE 0871 Class A above 150 kHz. Typical margins >3 dB at all frequencies and line/load conditions.
** Voltage Adjust:** Factory set on GLC40, however, adjust potentiometer standard on all GLX50 and GLX65.
** Safety:** All GLC models are approved to UL1950, CSA22.2 No. 450, and EN60950. All GLM models approved to UL2601, CSA22.2 No. 601.1 and EN60601-1.
** Input Current:** Maximum input current at 120 VAC, 60 Hz with full rated load not to exceed 1.3 A for GLC40, 1.5 A for GLX50, 1.7 A for GLX65 singles and 2.0 A for the GLX55 multis.
** Hold Time:** 15 mS minimum at full load and nominal line (115 VAC).
** Overload Protection:** Fully protected against short circuit and output overload on all outputs. Short circuit protection is cycling type power limit.
** Transient Response:** Main output: 500 μSec typical response time for return to within 0.5% of final value for a 50% load step within the regulations limits of minimum and maximum load, dl/dt<0.2 A/μSec. Maximum voltage deviation is 3.5%.

UL2601 and IEC601-1.* Dimensions — In. (L × W × D):** Multiple Output — 7.00 × 4.25 × 1.30; Single Output — 5.75 × 3.40 × 1.56 ** Input Current.** Maximum input current at 90 VAC, 60 Hz with full rated output load not to exceed 2.9 A. ** Hold-Up Time:** 20 mSec minimum from loss of AC input at full load, nominal line (120 VAC). ** Output Power.** Normal continuous output power is 75 W for unrestricted natural convection cooling; 110 W with 26 cfm airflow. During peak load conditions output regulation may exceed total regulation and noise limits. ** Total Regulation. Adjustable Outputs:** Maximum deviation from set point. ** Fixed Outputs:** Maximum deviation from nominal. ** Power Limit.** Factory set to begin power limiting at approximately 120 W (GLC75-5 is set at approximately 100 W). Fully protected against short circuit and output overload. Short circuit protection is cycling type power limit. ** Output Noise.** 0.5% RMS, 1% Pk-Pk, 20 MHz bandwidth, differential mode. Measured with noise probe directly across output terminals of the power supply. ** Transient Response. Main Output:** 500 mSec typical response time for return to within 0.5% of final value for a 50% load step change, Di/Dt <0.2 A/mSec. ** Maximum Voltage Deviation:** 3.5%. ** Startup/Shutdown Overshoot:** Less than 3%. ** Voltage Adjust.** Factory set on standard multiple-output units. All single-output models and multiple-output models with optional potentiometer are adjustable ±5%. ** Note:** Output #1 must not be more than 1% below nominal to achieve full output regulation on output #2. High voltage settings may degrade the reliability of the unit due to excessive power dissipation in some outputs. ** Overvoltage Protection.** Built in on main output. ** Reverse Voltage Protection.** Protected against inadvertent application of reverse voltage up to 1 times rated current of the reversed output. ** Efficiency.** 72-85% depending on model. ** Turn-On Time.** Less than 1 second at 120 VAC, 25°C (inversely proportional to input voltage and thermistor temperature). ** Input Protection.** Internal AC fuse provided. Designed to blow only if a catastrophic failure occurs in the unit — fuse does not blow on overload or short circuit. ** Inrush Current.** Inrush limited by internal thermistors. Inrush at 240 VAC, averaged over the first AC half-cycle under cold start conditions will not exceed 37 A. ** Temperature Coefficient.** 0.03%/°C typical on all outputs. ** Environmental.** Designed for 0 to 50°C operation at full rated output power; derate output current and total output power by 2.50% per °C between 50-70°C.
