cold start 25 °C (First surge only, not including the current flow into
the EMI filter)14A typ. (100 V a-c, 100% load); 28A typ. (200 Va-c, 100% load).
LEAKAGE CURRENT:
0.29mA typ, 0.45mA max at 100V a-c and 60 Hz (operating in conformance with
Den-An),
0.40mA typ, 0.65mA max at 240V d-c and 60 Hz (operating in conformance with IEC
950 and UL1950).
POWER FACTOR:
0.99 typ. at 100 Va-c, 0.96 typ. at 240 Va-c.
STABILIZATION:
Source Effect: (85 to 132Va-c, 170-265 Va-c) 0.1% typ., 0.2% max.
Load Effect: (0% - 100% of rated output current) 0.2% typ., 0.4% max.
Temperature effect: (-10 to 71°C) 0.5% typ., 1.0% max.
Combined effect (source, load, temperature): 0.9% typ., 1.8% max.

TRANSIENT RECOVERY:
A step load change from 50% to 100% of rated output
current in 50 microseconds or more, produces no more than 4% output voltage excur-
sion. Recovery time is 1ms maximum.
