Also programmable by 2-5 V : 89% at 230 V AC input. : 5.10-5 per C : 3.10-4 during 8 hrs under constant conditions, after 1 hr warm up. : Better than 10 mV : Better than 5 mV : Max. 7 mV rms, 20 mV pp : Less than 0.05 Ohm up to100kHz : 0.3 milliseconds to recover within 100 mV after 50 to 100% load step. Max deviation 300 mV. : 15 ms at 115 or 230 V AC input and full load. 30 ms at half load. : Up to 500 V total Voltage. Use R+ connection via build-in Schottky diode to separate the out

• Under voltage alarm contact : changes over when output voltage drops to 10% below the set value. Contact rating 100 mA / 30 V. • Remote control : Is possible with a 10 KΩ potmeter. • Remote programming : Output voltage is programmable with 2-5 V, corresponding with 12-30 V (24-60 V). Programming speed is 100 ms from 12-30 V (24-60 V) at max. current. Programming input is not isolated ( connected to - output) • Remote sensing : max. 3 V per load lead. however the sum of voltage across load + leads cannot exceed 30 V (60 V) With parallel operation remote sensing is not recommended. • Remote on/off...
