DC/DC Converters

THL 10WI Series

10 Watt

Input Specifications

Input current at no load (at nominal input voltage)

24 V models: 30 mA typ.

48 V models: 20 mA typ.

Input current at full load (at nominal input voltage)

24 V; 3.3 VDC models: 400 mA typ.

24 V; other models: 500 mA typ..

48 V; 3.3 VDC models: 200 mA typ.

48 V; other models: 250 mA typ.

Start-up voltage / under voltage lockout

24 V models: 9 VDC / 8.5 VDC (or lower)

(hysteresis for assertive on)

48 V models: 18 VDC / 17 VDC (or lower)

(long term operation at undervoltage will

demage the converter!)

Surge voltage (1 sec. max.)

24 Vin models: 50 V max.

48 Vin models: 100 V max.

Conducted noise (input)

EN 55022 class A, FCC part 15, level A

without external components

Recommended input fuse (slow blow)

24 V models: 2000 mA

48 V models: 1000 mA

Output Specifications

Voltage set accuracy

±2 %

Regulation

– Input variation (Vmin – Vmax)

1.0 % max.

– Load variation

single output models: 1.2 % max. (15 – 100 % load)

dual output models: 2.0 % max. (15 – 100 % balanced load)

Minimum load

15 % of rated max. current (operation at lower

load condition will not damage the converters.

However, they may not meet all listed specifications)

Ripple and noise (20 MHz bandwidth)

60 mVp-p typ.

Temperature coefficient

±0.02 %/K

Output current limitation

>110 % of Iout max.

Short circuit protection

indefinite, automatic recovery

Transient response setting time

300 µs typ. (25 % load step change)

Maximum capacitive load

3.3 VDC models: 560 µF

5 VDC models: 560 µF

12 VDC models: 150 µF

15 VDC models: 150 µF

24 VDC models: 68 µF

±5.0 VDC models: 220 µF (each output)

±12 VDC models: 100 µF (each output)

±15 VDC models: 100 µF (each output)
